Cleanroom Door Gasket
A black hollow-bulb gasket retained in a cleanroom door-frame channel to create continuous compression around the opening.
- Retained Bulb Profile
- Controlled Closing Force
- Continuous Frame Compression
- Replaceable Kerf Mount
Product Introduction
The cleanroom door gasket combines a hollow EPDM compression bulb with a flexible neck and arrowhead-style retaining foot. The retainer locks into a matching kerf or aluminum channel around the cleanroom door frame, keeping the seal aligned during repeated opening and closing. When the leaf engages the bulb, the hollow chamber deforms progressively to close perimeter tolerances while limiting load on hinges, latches and automatic operators.
Key Features
The arrowhead foot locks mechanically into a continuous frame channel without exposed fasteners.
Defined corner joints preserve the seal path around mitred stainless or aluminum frames.
The removable profile can be replaced independently when wear or permanent compression develops.
Customer Product Concerns
A cleanroom door perimeter must close reliably without creating excessive latch force or allowing the gasket to pull out of its frame channel.
An overly stiff seal prevents consistent latching and accelerates hardware wear.The hollow bulb compresses gradually and is sized for the actual door-frame gap.
Adhesive-backed strips creep or detach during repeated cleaning and door cycles.A shaped retaining foot locks into the frame kerf for positive mechanical location.
Open corner cuts create air-leak paths at the most difficult frame transitions.Joined or molded corner sections maintain continuous compression around the complete perimeter.
A damaged seal can require disruptive frame disassembly.The replaceable insert pulls from the channel and a matching new profile presses into the existing retainer.
Typical Applications
Hinged cleanroom personnel doorsPass-through chamber doorsStainless equipment access doorsPharmaceutical corridor doorsControlled-environment service hatches
