STJH hollow silicone gasket with a rounded bulb opening shown against white.

STJH-AIRTIGHT-CLEANROOM-DOOR-GASKET-SILICONE-HOLLOW

Airtight Cleanroom Door Gasket Food-Grade Silicone Hollow

Select a hollow silicone bulb when the door needs a compliant passive perimeter contact.

Hollow geometry provides room for controlled compression.
Silicone construction differs from a solid EPDM lip.
The replaceable extrusion can follow a continuous perimeter.

商品紹介

The gasket uses a hollow silicone cross-section that deforms under the closing force of the leaf. Unlike a thin lip, the bulb presents a broader resilient contact region around the door perimeter. It is produced as an extrusion for a compatible retaining arrangement, with length and cross-section matched to the opening. The material family is used for food-related and controlled-environment sealing applications where silicone is the specified elastomer.

Solutions for Your Application

A narrow lip does not provide the desired contact geometry.

The hollow bulb creates a broader compression region.

The seal must fit a particular perimeter gap.

Specify a suitable bulb section and retaining profile.
