NGP OV633A-36 – Frequently Asked Questions

1) What lengths does the NGP OV633A nylon brush door sweep come in?
Three lengths: 36 inch, 48 inch, and 120 inch. The 36 inch covers a standard single door, 48 inch suits wider openings, and the 120 inch stock length lets you cut down on site or gasket a pair of doors from one piece.
2) Will a brush sweep like the NGP OV633A seal an uneven or out-of-level door bottom better than a rubber sweep?
That is the reason to pick brush. The synthetic polyamide filament in the OV633A flexes over high spots and returns to shape, so it keeps contact where a solid neoprene or vinyl blade would hang up or deform. A rubber insert seals tighter against air and water on a flat, true threshold, so for weather sealing look at something like the Cal-Royal BTN-112, which uses an extruded aluminum retainer with a neoprene insert. Brush is the choice for dust, debris, insects, and doors with sloppy clearance.
3) Does the NGP OV633A door sweep come with mounting screws?
Yes, #6 x 3/4 inch stainless steel sheet metal screws are furnished. The holes in the aluminum base are slotted, so you can set the brush height against the floor before you tighten down. If you would rather not drill the door, NGP offers the sweep with a Fast Attach Tape (FATT) option instead of screws.
4) How much gap will a 1 inch brush door sweep close?
The OV633A carries a 1 inch brush, so the filament length gives you roughly an inch of reach below the aluminum base to take up door-to-floor clearance. Mount the base so the brush just brushes the floor at the tightest point of the swing, then use the slotted holes to fine tune. If your undercut is much larger than that, you want a taller brush or a door shoe rather than a 1 inch sweep.
5) What is the closest brush door sweep equivalent to the NGP OV633A?
The Pemko 29326NB is the nearest match. Like the NGP OV633A, it is a brush door bottom sweep on a clear anodized aluminum base, and it is offered in a 36 inch length, which is one of the three lengths the OV633A comes in alongside 48 inch and 120 inch. The main difference in how they mount: the OV633A uses slotted screw holes on the face of the retainer with #6 x 3/4 inch stainless steel sheet metal screws furnished, while the 29326NB uses a concealed fastener design so no screw heads show on the retainer face. If the specification calls for exposed slotted holes for field adjustment after hanging, the OV633A is the one that gives you that; if the visible detail matters on a finished opening, the Pemko concealed design is the alternative.
6) Should I use a brush sweep or a neoprene sweep on a commercial exterior door?
They seal differently. The NGP OV633A carries a synthetic polyamide nylon brush on an aluminum alloy 6063 T5 base, rated from -70 F to 425 F, and the brush conforms to uneven or out-of-level thresholds and sweeps dust, debris and insects without binding. The Cal-Royal BTN-112 takes the other approach, pairing an extruded aluminum retainer with a neoprene insert, which contacts the sill as a continuous wiping blade rather than as bristles. Brush is the usual pick where the floor is rough concrete, tile or carpet transitions that a solid blade would drag on; a neoprene insert is the usual pick where you want a more continuous contact line against a flat sill. Both mount to the face of the door bottom on an aluminum retainer.
7) We need a GREENGUARD certified door sweep for a LEED project - is the NGP OV633A it?
The NGP OV633A is built with REACH and RoHS compliant materials, which addresses restricted substances in the brush and base, but that is a materials compliance statement rather than an indoor air quality certification. If the submittal specifically requires GREENGUARD Gold, the Pemko 345V door bottom sweep carries a GREENGUARD Gold certified Eco-V insert and is the one to put on the schedule. Note the 345V seals with a flexible insert rather than a nylon brush, so if the opening needs brush contact over an uneven floor you are choosing between sealing style and the certification line item.
8) What do I use instead of the NGP OV633A if water is driving under the door?
A brush sweep is built to stop dust, debris and insects, and the NGP OV633A is described for that duty. Driving rain on an exterior opening is a different problem, and the part that addresses it is the Pemko 3452, a surface plate rain drip door bottom. A rain drip mounts on the exterior face above the door bottom and throws water clear of the joint rather than sealing the gap at the floor. On a weather-exposed opening the two are commonly used together, with the drip handling the water and a sweep such as the OV633A handling the gap at the sill.
9) Can I use this NGP brush sweep on a door near a kitchen, boiler room, or other high-heat area?
The OV633A is rated from -70 F to 425 F, which covers mechanical rooms, kitchen back-of-house, and unconditioned loading areas as well as cold-climate exteriors. The base is 6063-T5 aluminum alloy with an anodized finish for corrosion resistance.
10) Is the NGP OV633A rated for commercial door traffic or is it a residential sweep?
Commercial. It is built for office buildings, schools, hospitals, retail, warehouses, government buildings, and multi-tenant residential, using a 6063-T5 aluminum base rather than the thin stamped retainers typical of residential sweeps. For a property manager standardizing across a building, the same profile in the 120 inch stock length can be cut to fit a mix of door widths.
11) Does this door sweep meet REACH and RoHS requirements for a government or healthcare spec?
The OV633A uses REACH and RoHS compliant materials, which is what most public and institutional environmental specs are asking for on gasketing. If the spec instead calls for a low-emitting indoor air quality certification, the Pemko 345V door bottom sweep carries a GREENGUARD Gold certified Eco-V insert.
12) What else could I use instead of the NGP OV633A brush sweep?
Among comparable door bottom sweeps, the Pemko 29326NB is a brush sweep in clear anodized aluminum with a concealed fastener design, which is the closer choice if you do not want screw heads showing on the door face. The Pemko 56 Series and Pemko 345V use an Eco-V insert rather than brush, better on a flat threshold for air and water. The Pemko 3452 is a surface plate rain drip door bottom, a different part entirely, meant to shed water away from the door bottom on exterior openings, often used along with a sweep rather than in place of one.
13) Will a brush sweep keep insects and rodents out of a warehouse door?
That is the intended use. The OV633A seals against dust, debris, and insects, and the nylon brush is moisture resistant and retains insecticides well, which is why brush sweeps get specified on industrial and warehouse doors. It is a barrier sweep, not a compression weather seal, so for driving rain on an exterior opening pair it with a rain drip such as the Pemko 3452.
14) Is the Pemko 56 Series a drop-in replacement for an NGP OV633A on a 36 inch door?
They cover the same 36 inch opening width - the Pemko 56 Series is sold in a 36 inch length and the NGP OV633A is offered in 36 inch as well - but they are not the same seal. The 56 Series uses an Eco-V insert, while the OV633A uses a 1 inch gray synthetic polyamide nylon brush on an anodized aluminum base. Retainer profiles and screw hole spacing differ between manufacturers, so plan on drilling fresh pilot holes rather than reusing the existing pattern. If you are standardizing a building and already have OV633A on other doors, staying with the NGP keeps the brush height and base finish consistent across the fleet.
15) I need to sweep several double doors and a set of oversized openings - which sweep covers that in one piece?
The NGP OV633A is stocked in a 120 inch length in addition to 36 inch and 48 inch, so a single stick can be cut down to cover a pair of leaves or an oversized opening without a splice. Among comparable brush and insert sweeps, the Pemko 29326NB is specified at 36 inch and the Pemko 56 Series at 36 inch, which are single-leaf lengths. For a fleet of mixed door widths, ordering the 120 inch OV633A and cutting to size on site keeps one part number across the job and one brush height on every opening.
16) For a boiler room or kitchen door, does the NGP OV633A hold up better than a rubber insert sweep?
Heat is where the brush construction separates itself. The NGP OV633A runs from -70 F to 425 F on a synthetic polyamide brush and an aluminum alloy 6063 T5 base, so it is the one to specify on mechanical rooms, boiler rooms and kitchen service doors. The comparable insert-style sweeps seal with elastomer strips instead - the Cal-Royal BTN-112 with a neoprene insert, and the Pemko 345V and Pemko 56 Series with Eco-V inserts - which are the conventional choice on conditioned interior and standard exterior openings. Match the sweep to the ambient temperature at the opening, not just to the door width.
17) Can I cut the NGP OV633A sweep down to fit a narrower door?
Yes. The base is extruded 6063-T5 aluminum and the brush is filament, so it cuts to length with a hacksaw or miter saw and the brush trims with shears. The 120 inch length is the one to order when you are fitting several openings from one piece or need a width between the 36 and 48 inch sizes. Cut before you drill, since the mounting slots need to land clear of the door edges.
