NGP 161SA-36 – Frequently Asked Questions

1) What lengths does the NGP 161SA perimeter seal come in, and how do I cover a full door opening?
The 161SA is stocked in two lengths: 36 inches and 84 inches. For a standard single opening you typically run one 36 inch piece across the head and two 84 inch pieces down the jambs, cut to fit. Order the head and jamb pieces separately rather than expecting a packaged set.
2) Can the NGP 161SA silicone perimeter seal be used on a fire rated door assembly?
Yes. The 161SA is BHMA certified to ANSI/BHMA A156.22 performance tests for heat, cold, air infiltration and smoke infiltration, and it is called out for fire rated door assemblies. The silicone gasket is flame resistant, which is also why it is recommended in rooms protected by FM200 or Halon suppression systems.
3) Will a silicone door seal hold up in a walk-in freezer or on an exterior door in a hot climate?
Temperature range on the 161SA gasket runs from -100 F to 500 F, and the siloxane synthetic rubber stays flexible and keeps its memory at both ends of that range. It also resists ozone, UV and aging and is moisture resistant, so it handles sun-exposed exterior openings as well as cold storage. A vinyl-insert gasket, like the Cal-Royal PG-601, is the more common general-purpose choice but does not carry that temperature claim in our record.
4) Do I need to buy screws separately for the NGP 161SA perimeter seal?
No. #6 x 3/4 inch stainless steel sheet metal screws come with the seal. The mounting holes are slotted, so you can set the gasket in, snug the screws, and shift the retainer in or out against the door face to dial in compression before final tightening. That adjustment is what gets a smoke seal to actually seal on a door that is slightly out of square.
5) What is the difference between the NGP 161SA perimeter seal and the Cal-Royal PG-601 gasketing?
Both are aluminum channel perimeter gasketing for commercial door frames, but the sealing element differs. The NGP 161SA uses a dense black silicone gasket of synthetic rubber polymer siloxane that stays flexible from -100 F to 500 F and is BHMA certified to ANSI/BHMA A156.22 for heat, cold, air infiltration and smoke infiltration. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert. Silicone is the material chosen where extreme heat, flame resistance, or FM200 and Halon fire suppression areas are involved; vinyl is a common choice for general weather sealing on exterior openings.
6) I need perimeter gasketing on a fire-rated door assembly for smoke sealing. Is a vinyl insert seal acceptable, or do I need silicone?
For a fire-rated assembly where smoke infiltration is part of the requirement, the NGP 161SA is the one to specify: it is BHMA certified to the ANSI/BHMA A156.22 performance tests for heat, cold, air infiltration and smoke infiltration, and its silicone gasket is flame resistant and rated to 500 F. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing with a vinyl insert, which is a weather-sealing configuration rather than a high-temperature one. Confirm the seal is listed for the specific door and frame label you are working to before ordering either.
7) What is the NGP 161SA seal frame made of, and will it corrode in a coastal or wash-down area?
The retainer is 6063 T5 temper aluminum alloy with a satin aluminum clear anodized finish. Anodizing gives it corrosion resistance for commercial use, and the fasteners supplied are stainless steel, so you are not mixing a plated screw into a damp opening.
8) Is the NGP 161SA a residential weatherstrip or a commercial product?
It is a commercial-duty perimeter seal, intended for office buildings, healthcare, schools, government buildings and industrial plants. It mounts to the frame stop and seals the perimeter of the opening; it is not a door bottom or threshold, so a sweep or automatic door bottom is still needed to close the gap at the sill.
9) Silicone perimeter seal or vinyl insert gasketing, which should I spec?
Go silicone, like the NGP 161SA, when the opening is fire rated, smoke rated, sun exposed, or sees extreme heat or cold, since that gasket is A156.22 certified for heat, cold, air and smoke infiltration and rated -100 F to 500 F. An aluminum channel gasket with a vinyl insert, such as the Cal-Royal PG-601, is the simpler option for ordinary interior sound and light sealing where none of those conditions apply.
10) The opening needs a seal at the bottom of the door, not around the frame. Does the NGP 161SA work?
No. The NGP 161SA is a perimeter seal, meaning it mounts to the head and jambs of the frame and seals against the door face; it is furnished with #6 x 3/4 inch stainless steel sheet metal screws and slotted holes for adjustment. For the bottom of the door you want a door shoe or automatic door bottom instead. Cal-Royal's PG-601 aluminum channel perimeter gasketing is catalogued within their Door Shoes Series, so that family is worth reviewing for a bottom-of-door product, but the PG-601 itself is perimeter gasketing and mounts the same way as the 161SA.
11) Can I mix the NGP 161SA and the Cal-Royal PG-601 across doors in the same building?
Mechanically yes, since both are surface-applied aluminum channel perimeter gasketing for commercial frames, but you will see two different sealing materials and finishes on the job. The NGP 161SA is aluminum alloy 6063 T5 with a satin aluminum clear anodized finish and a dense black silicone gasket; the Cal-Royal PG-601 is an aluminum channel with a vinyl insert. Where a facility wants one appearance and one gasket performance profile across every opening, standardize on a single model. The 161SA comes in 36 inch and 84 inch lengths, which covers heads and jambs on a standard opening from one part number.
12) What color is the gasket on the NGP 161SA, and how does it look against an anodized frame?
The gasket is dense black silicone, carried in a satin aluminum clear anodized retainer. That black-on-clear-anodized combination is the standard commercial look and matches typical aluminum frames and storefront trim.
13) Is there a heavier aluminum version of the 161 perimeter seal for military spec jobs?
Yes, a .07 aluminum construction is offered where military specifications call for it. The standard 161SA otherwise uses the 6063 T5 aluminum retainer with the silicone gasket.
