NGP 600A 48 – Frequently Asked Questions

1) Can I use the NGP 600A brush seal on a 3-hour fire rated hollow metal door?
Yes. The NGP 600A 1/2 inch nylon brush seal is UL certified to CAN/ULC-S104 and ANSI/UL10B for hollow metal fire doors up to 3 hours, and for wood fire doors up to 90 minutes. It complies with NFPA 80 and NFPA 252. Note the split: if your opening is a wood fire door, the ceiling is 90 minutes regardless of what the door assembly itself is rated for.
2) Is the NGP 600A brush seal approved for positive pressure fire door assemblies?
It is. The 600A carries UL certification to ANSI/UL10C for positive pressure applications, with IBC, NFPA 80 and NFPA 252 compliance. It is also certified to ANSI/UL1784 Category H for smoke and draft control on positive pressure hollow metal fire doors up to 3 hours and wood fire doors up to 90 minutes. That combination is what an inspector looks for on a smoke barrier opening.
3) What lengths does the NGP 600A nylon brush seal come in for a full door frame?
Ten lengths: 36, 42, 48, 72, 83, 84, 96, 108, 120 and 144 inches. For a standard single opening you typically take one head piece and two jamb pieces, so an 83 or 84 inch piece covers the jambs and a 36 or 42 inch piece covers the head. The 108, 120 and 144 inch pieces are there for tall openings and for cutting down on the job.
4) Is the Cal-Royal PG-601 perimeter gasketing a substitute for the NGP 600A nylon brush seal?
They seal the same perimeter but with different sealing elements, so they are not drop-in equals. The NGP 600A uses a 1/2 inch synthetic polyamide brush in an aluminum alloy 6063 T5 frame, UL certified for hollow metal fire doors up to 3 hours and wood fire doors up to 90 minutes, with a temperature range of -70 F to 425 F and positive pressure certification to ANSI/UL10C. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing that seals with a vinyl insert. A brush element sweeps against an irregular or out-of-plumb stop and tolerates high heat and abrasion, while a vinyl insert compresses against the stop for a continuous contact seal. On a labeled fire door assembly, the substitution has to be made on the certification the opening requires, not on the frame profile alone.
5) Will a nylon brush seal hold up on an exterior door or a boiler room door with extreme temperatures?
The 600A brush operates from -70 F to 425 F, which covers unconditioned mechanical spaces, freezer vestibules and exposed exterior openings alike. The frame is aluminum alloy 6063 T5 temper and the brush is synthetic polyamide, so moisture is not an issue, and it is BHMA certified to ANSI/BHMA A156.22 heat and cold performance tests.
6) Should I use a brush seal or a vinyl bulb gasket on my door frame?
Brush versus bulb comes down to what the door does. The 600A's synthetic polyamide brush sweeps rather than compresses, so it tolerates a door that is out of alignment or gets slammed hard, and it has the abrasion resistance and memory retention for high-cycle traffic. A compression bulb like the vinyl insert on the Cal-Royal PG-601 perimeter gasketing seals tighter against a door that closes true and consistently. On a fire rated opening, the deciding factor is usually the listing, and the 600A carries UL certification to 3 hours on hollow metal.
7) Do I need to buy separate fasteners to install the NGP 600A brush seal?
No, the mounting hardware ships with it. Each piece comes with #6 x 3/4 inch stainless steel sheet metal screws, and the holes in the aluminum retainer are slotted so you can shift the seal in or out against the door face before you tighten down. That adjustment matters on a frame that is not perfectly square.
8) Is the NGP 600A brush seal listed in the BHMA Certified Products Directory?
Yes. The 600A is BHMA certified to ANSI/BHMA A156.22 performance standards and is listed in the BHMA Certified Products Directory. If your facility standardizes on BHMA certified gasketing for procurement or for a state fire marshal review, this one is documented in the directory rather than only claiming compliance.
9) What should I use on a non-rated interior door instead of a fire rated brush seal?
For an opening with no label to protect, a vinyl insert perimeter gasket such as the Cal-Royal PG-601 covers the ordinary job of closing the gap at the head and jambs, using an aluminum channel with a vinyl sealing insert. The NGP 600A brush seal is built for the cases where the certification matters or the conditions are harsh: it carries UL certification to CAN/ULC-S104 and ANSI/UL10B, ANSI/UL1784 Category H smoke and draft control, BHMA certification to ANSI/BHMA A156.22, and an operating range of -70 F to 425 F. If the door is a labeled fire or smoke assembly, the gasketing has to carry the listing the assembly was tested with, so the brush seal is the one that answers to NFPA 80.
10) Is the NGP 600A brush seal rated for air infiltration on an exterior opening?
It has been tested to ASTM E283, the standard method for determining air leakage rates through exterior windows, curtain walls and doors. That is the test a spec writer references when the drawing calls for an air infiltration number on a perimeter seal.
11) What finish does the NGP 600A brush seal retainer come in?
Satin aluminum clear anodized. It is a mill-toned aluminum that reads neutral against hollow metal frames finished in gray or bronze paint, and it is the same finish across every length, so a partial replacement on one opening will match the seals already installed on the rest of a floor.
12) Is the NGP 600A brush seal meant for commercial doors or will it work on a house?
This is a commercial-duty gasket. It is built for fire rated and smoke rated openings in healthcare, schools, industrial plants, government buildings and multi-tenant residential fire rated assemblies. It will physically install on a residential door, but the fire and smoke certifications that justify the aluminum-and-polyamide construction only pay off on a rated opening.
