NGP I-624A 48 – Frequently Asked Questions

1) Can a nylon brush seal be used on a fire rated door, or does it void the label?
The NGP I-624A nylon brush seal is UL certified to CAN/ULC-S104, ANSI/UL10B and ANSI/UL10C, so it can go on a labeled opening without breaking the rating. It is certified for fire rated hollow metal doors up to 3 hours and wood fire doors up to 90 minutes, and complies with IBC, NFPA 80 and NFPA 252. Note the split: 3 hours only applies to metal. On a wood fire door you are capped at 90 minutes regardless of the door's own label.
2) Should I use a nylon brush seal or a vinyl bulb gasket on my doors?
Brush versus vinyl is really a question of what the door does. Nylon brush like the I-624A sweeps rather than compresses, so it tolerates a door that drags, racks, or gets slammed thousands of times a day, and it survives -70 F to 425 F, which vinyl will not. A compression gasket seals tighter against air and light on a door that closes square every time. If you want the vinyl approach, the Cal-Royal PG-601 is an aluminum channel perimeter gasket with a vinyl insert. For a fire rated opening, the I-624A is the one carrying UL certification.
3) Can I use Cal-Royal PG-601 perimeter gasketing on a fire rated door instead of an NGP brush seal?
For a rated opening, specify the NGP I-624A: it carries UL certification to CAN/ULC-S104, ANSI/UL10B and ANSI/UL10C for positive pressure, and complies with IBC, NFPA 80 and NFPA 252 for hollow metal doors up to 3 hours and wood fire doors up to 90 minutes. The Cal-Royal PG-601 is aluminum channel perimeter gasketing with a vinyl insert and suits non-rated perimeter sealing where the inspector is not checking a labeled assembly. The I-624A comes in 48 inch and 120 inch lengths, so a single 120 inch piece covers a standard head and the 48 inch covers most jamb runs when cut.
4) What lengths does the NGP I-624A brush seal come in?
Two lengths are stocked: 48 inch and 120 inch. The 48 inch piece covers a standard door head or a single jamb leg on most openings; the 120 inch piece is the one to order when you are gasketing full jamb legs on a tall opening or cutting several head pieces from one stick. Aluminum extrusion cuts clean with a miter saw, and the screw holes are slotted, so trimming a 120 inch piece to length does not cost you fastening points.
5) Does the NGP I-624A come with screws, or do I need to buy fasteners separately?
Fasteners are in the box. Each piece ships with #6 x 3/4 inch stainless steel sheet metal screws. Stainless matters on an exterior opening where a plated screw would rust and stain the anodized frame. The holes are slotted rather than round, so you can shift the seal up or down against the door face after the screws are started and set brush contact without pulling the piece back off.
6) Will a brush seal hold up on a hot kitchen or boiler room door?
Yes. The synthetic polyamide brush and 6063 T5 aluminum frame are rated from -70 F to 425 F, which covers commercial kitchen, boiler room, and mechanical room doors as well as unheated exterior openings in cold climates. The polyamide filament keeps its memory instead of taking a set, so it springs back to the door face rather than staying flattened the way a heat-softened vinyl bulb does.
7) Can I get the NGP brush seal with a black brush instead of gray, or with adhesive tape instead of screws?
Both options exist on the I-624A. The -BB suffix gets you a black brush in place of the standard gray, which is what you want against a dark bronze or black door so the gasket line disappears. The FATT option is Fast Attach Tape, for openings where you cannot drill the frame. Screw mounting is the default and is what the included #6 x 3/4 inch stainless screws are for.
8) Which perimeter seal holds up better against a door that drags or sweeps across the stop?
The NGP I-624A brush is synthetic polyamide chosen for flexibility, memory retention and abrasion resistance, so the filaments recover their shape after repeated sweeping and the seal keeps contact on a high traffic door; it is also moisture resistant and can retain insecticides where pest control is part of the scope. The Cal-Royal PG-601 relies on a vinyl insert in an aluminum channel, which is a compression contact rather than a sweeping one. On a door that scrubs the stop, the brush is the more forgiving of the two.
9) Is the NGP I-624A brush seal suitable for residential doors or is it a commercial product?
It is specified as a commercial product. The I-624A is built for institutional traffic: anodized 6063 T5 aluminum carrier, polyamide brush, UL fire certification. Property managers do put it on multi-tenant residential fire doors, which is a listed application, but the reason is the fire label on those doors, not the finish of the apartment. For a single-family exterior door with no rated assembly, a compression perimeter gasket such as the Cal-Royal PG-601 is the more usual choice.
10) Will a nylon brush seal keep bugs and rodents out of a door gap?
The brush is dense polyamide and it will retain insecticide, which is why pest control contractors specify brush over bulb gasket on loading dock and back-of-house doors. It also resists moisture, so a treated brush does not wash out in the first rain. Understand what it is: brush blocks passage, it does not form an airtight compression seal the way a vinyl bulb does. For pest exclusion that is the right trade, since a brush keeps working on a door that no longer closes perfectly square.
11) Does the NGP I-624A meet REACH and RoHS requirements for a government or healthcare spec?
REACH and RoHS compliant, both stated for the I-624A materials. That covers the usual environmental line item on government, municipal and healthcare submittals. On the fire side the same piece carries UL certification to CAN/ULC-S104, ANSI/UL10B and ANSI/UL10C, including positive pressure testing, so one submittal covers both the environmental and the life safety requirement on a rated barrier.
