NGP G622A-36 – Frequently Asked Questions

1) What lengths does the NGP G622A nylon brush seal come in, and which one do I need for a standard door?
Two lengths are offered: 36 inches and 96 inches. The 36 inch piece covers the head of a standard 3-0 door; for the jambs on a typical 7-0 opening you want the 96 inch length, which cuts down to size. A full perimeter on one door normally takes one 36 inch head piece plus two jamb pieces cut from 96 inch stock.
2) Can I use Cal-Royal PG-601 gasketing on a fire-rated door instead of the NGP G622A brush seal?
Confirm the rating before you substitute. The NGP G622A 1-3/4 inch nylon brush seal is approved for fire-rated metal doors up to 3 hours or wood doors up to 60 minutes, which is the spec most fire door schedules are written against. The Cal-Royal PG-601 is described as an aluminum channel perimeter gasketing with a vinyl insert; if your opening is labeled, specify the G622A so the fire rating and the -70 F to 425 F temperature range are both covered by the same part.
3) What is the difference between the NGP G622A nylon brush seal and the Cal-Royal PG-601 perimeter gasketing?
They seal the opening with two different mediums. The NGP G622A carries a synthetic polyamide brush in an aluminum alloy 6063 T5 housing, and the brush filament is what contacts the door. The Cal-Royal PG-601 is an aluminum channel perimeter gasketing that uses a vinyl insert as the sealing element. Both mount to the frame in an aluminum carrier, so the prep is similar, but the brush of the G622A sweeps across the door face and tolerates a wider gap and out-of-plumb condition, while a vinyl insert compresses against the stop for a tighter contact seal. Choose the brush where the door drags or the temperature swings, since the G622A is rated from -70 F to 425 F.
4) Does the NGP G622A brush seal come with fasteners, or do I need to buy screws separately?
Screws are included: #6 x 3/4 inch stainless steel sheet metal screws ship with the seal. The housing has slotted screw holes, so you can shift the seal in or out against the door face to set brush contact before you snug the screws down.
5) Will a nylon brush seal hold up in a freezer room or a high-heat mechanical room?
The G622A brush is synthetic polyamide rated from -70 F to 425 F, which covers walk-in freezer and cold storage vestibules at the low end and boiler or mechanical room doors at the high end. The brush is also moisture resistant, so wash-down and humid areas are within its range.
6) Should I use a brush seal or a vinyl bulb gasket on my doors?
Brush works better where the door sees heavy traffic or where debris, dust, or insects are the problem. The nylon filament sweeps rather than compresses, so it keeps its memory after thousands of cycles and won't take a set the way a compressed bulb can, and it won't drag or squeal on a door that's slightly out of alignment. A vinyl insert gasket like the Cal-Royal PG-601 aluminum channel perimeter gasketing is the better choice when you need a tighter air and sound seal on a door that closes squarely against the stop. Both mount to the frame in an aluminum channel.
7) For a warehouse door where the frame is out of square, is a brush seal or a vinyl insert gasket the better choice?
A brush handles the irregular gap better. The NGP G622A uses synthetic polyamide filament with excellent abrasion resistance, flexibility and memory, so it keeps sweeping the door even where the clearance varies along the jamb, and its slotted screw holes let you shift the housing during install to chase the gap. The Cal-Royal PG-601 relies on a vinyl insert in an aluminum channel, which seals best where the door closes consistently against the stop. On a true, well-hung opening the vinyl insert gives closer contact; on a racked or heavily used frame the brush is the more forgiving detail.
8) What finishes does the NGP G622A brush seal come in?
Mill aluminum (anodized) and dark bronze, and both are offered in the 36 inch and 96 inch lengths. Dark bronze is the usual pick when the frame is dark bronze anodized or painted dark; mill aluminum blends with clear anodized aluminum frames and standard hollow metal.
9) Does the NGP G622A brush seal meet REACH and RoHS requirements for a government or healthcare spec?
Yes, the materials in the G622A brush seal are REACH and RoHS compliant, which is what most public agency, healthcare, and institutional submittals ask for on gasketing.
10) I need to seal a gap under a pest-prone exterior door. Will this brush seal help?
It will. The G622A brush is moisture resistant and retains insecticides well, and the filament sweeps across the gap rather than relying on a hard compression seal, which is why brush is commonly used at door perimeters where insects and rodents are the issue. Mount it to the frame with the slotted holes so you can set the brush to just kiss the door face.
