NGP 172VA 204 – Frequently Asked Questions

1) Can the NGP 172VA seal be used on a 3-hour fire rated hollow metal door?
Yes. The 172VA concealed fastener seal is UL certified for hollow metal fire doors rated up to 3 hours, and up to 90 minutes on wood fire doors. Certifications cited are CAN/ULC-S104 and ANSI/UL10B, with ANSI/UL10C for positive pressure. If your opening is a wood fire door with a rating above 90 minutes, this is not the seal for it.
2) Does the NGP 172VA meet positive pressure code requirements for fire doors?
It does. The 172VA is certified to ANSI/UL10C, which is the positive pressure test, and the seal is stated to meet IBC, NFPA 80 and NFPA 252 requirements. That is the combination an inspector looks for on a labeled fire door assembly in a hospital, school or multi-tenant building.
3) Is the Cal-Royal PG-601 a direct substitute for the NGP 172VA door seal?
Both are aluminum channel perimeter gaskets with a vinyl insert, so they address the same job of sealing the head and jambs of a commercial opening. The difference that decides it is fire certification: the NGP 172VA is UL certified to CAN/ULC-S104 and ANSI/UL10B for hollow metal fire doors up to 3 hours and wood fire doors up to 90 minutes, and carries ANSI/UL10C positive pressure certification for IBC, NFPA 80 and NFPA 252 compliance. The Cal-Royal PG-601 is described as aluminum channel perimeter gasketing with a vinyl insert. On a labeled fire door assembly, use the seal whose fire and positive pressure certification you can document.
4) How long is the NGP 172VA seal and how do I use 204 inches on a standard door?
The gasket runs 204 inches in one piece. On a standard single opening you cut it to length: two jambs plus the head. The 204 inch run is there so tall or oversized openings, or a continuous run across a pair, can be done without splicing mid-jamb.
5) Do I need to buy screws separately for the NGP 172VA door seal?
No. Six stainless steel sheet metal screws, 3/4 inch, ship with the seal. The screw holes are slotted, so you can shift the housing slightly against the stop to set gasket compression before final tightening.
6) Will the NGP 172VA hold up on an exterior door in cold weather?
The rated service range is 0 F to 140 F, and the seal has been air infiltration tested to ASTM E283 for exterior use. Below 0 F conditions fall outside the stated range, so for a freezer or an unheated sub-zero exposure look at a different gasket material.
7) What is an alternative to the NGP 172VA if I do not need a fire rating?
For a non-rated opening the Cal-Royal PG-601 aluminum channel perimeter gasketing with vinyl insert is the same basic idea: an aluminum channel carrying a vinyl seal along the jambs and head. Where the door is part of a labeled fire assembly, stay with the 172VA, since its UL fire and positive pressure certifications are what the inspection is checking.
8) What should I use on a non-rated interior door instead of the NGP 172VA?
The NGP 172VA carries fire and positive pressure certification that a non-rated interior opening does not require, so a plain aluminum channel perimeter gasket such as the Cal-Royal PG-601, which uses the same aluminum channel with a vinyl insert, covers the sealing function on an unlabeled door. Keep the 172VA where the assembly is labeled and the inspector will ask for the UL certification and NFPA 80 compliance.
9) Does the Cal-Royal PG-601 come in the same 204 inch length as the NGP 172VA?
The NGP 172VA is furnished as a 204 inch run in satin aluminum clear anodized, long enough to take a tall head or jamb leg in one continuous piece, and it ships with six 3/4 inch stainless steel sheet metal screws. The Cal-Royal PG-601 is an aluminum channel perimeter gasket with a vinyl insert; confirm the stock length you need before substituting, since a shorter stock length means splicing the run on a tall opening.
10) Will a door shoe work in place of the NGP 172VA seal?
No. The NGP 172VA is a concealed fastener perimeter seal with a vinyl gasket that mounts to the frame head and jambs to close the gap around the door edge. A door shoe mounts to the bottom of the door itself and seals to the threshold or sill, which is a different gap. The Cal-Royal PG-601 is catalogued in a Door Shoes Series but is itself an aluminum channel perimeter gasket with a vinyl insert, so read the description rather than the series name when matching a part to the perimeter of an opening. A full opening usually needs both a perimeter seal and a bottom seal.
11) What is the NGP 172VA gasket and housing actually made of?
Housing is aluminum alloy 6063 T5 temper with a satin aluminum clear anodized finish. The gasket is thermoplastic PVC made with a bio-based plasticizer, flame resistant and moisture resistant. That combination is why it holds up on exterior jambs as well as interior fire barriers.
12) What does concealed fastener mean on this NGP seal, and does it look better than a surface mounted gasket?
Concealed fastener means the mounting screws sit hidden within the housing rather than showing along the face of the extrusion, so the finished jamb reads as a clean anodized line. Functionally it seals the same as an exposed-fastener perimeter gasket; the difference is appearance and the slotted adjustment during install. On a lobby or corridor opening where the gasket is visible at eye level, that matters.
13) Is the NGP 172VA meant for commercial openings or will it work on a house door?
It is a commercial product. The 172VA is specified for fire-rated commercial door systems, healthcare fire barriers, schools, industrial separations, multi-tenant residential fire doors and hospitality. It will physically install on a residential door, but you are paying for fire certification and anodized aluminum that a house door does not need.
