商品紹介

The pass box door gasket forms the compressible perimeter interface between a transfer-chamber door and frame. Its hollow EPDM bulb deflects under latch pressure to accommodate small surface variation, while the carrier profile locates the seal along the mounting edge. Rounded corners reduce local stress and a single joined perimeter limits leakage paths. Replacement dimensions should match the existing groove or carrier, bulb height, compression allowance, corner radius and door closing force.

主要な特徴

A hollow bulb provides controlled recovery through repeated door cycles.

The continuous rectangular perimeter limits unnecessary joints in the sealing path.

Rounded corners avoid sharp folds that can restrict compression.

Dark EPDM provides a durable surface for routine cleanroom wipe-down.

お客様の製品に関する懸念事項

Seal performance depends on matching the profile and applying even compression around the complete door perimeter.

An undersized bulb leaves gaps where the door or frame is slightly uneven.Bulb height and compression range are selected to maintain contact around the full perimeter.

Excessive compression increases latch force and permanently deforms the seal.The installed gap is matched to the profile so the bulb works within its normal deflection range.

Poor corner forming causes kinks and localized leakage.Rounded corners preserve a consistent hollow section and smooth contact line.

An incompatible carrier profile will not remain seated during cleaning and door movement.The base geometry is matched to the existing groove, adhesive bed or mechanical retainer.
