Product Introduction

The boot combines a molded EPDM accordion neck with a rigid square double-flange base and four stainless corner fasteners. Its circular neck grips a compatible service while the convolutions accommodate limited movement.

Key Features

Accordion convolutions accommodate limited service movement.

A square double-flange base distributes clamping pressure.

Four stainless fasteners provide balanced retention.

Smooth molded EPDM supports routine wiping.

Customer Product Concerns

Rigidly sealed services can crack when movement shifts the pipe relative to the partition.

Movement stresses rigid sealant.The accordion neck flexes while maintaining contact.

Cutouts leave untidy edges.The broad flange covers the opening perimeter.

Uneven clamping leaves gaps.Four fasteners distribute retention.

Potting complicates service changes.The bolted assembly can be replaced.

Typical Applications

Cleanroom pipe penetrationsElectrical conduit transitionsEquipment utility connectionsFlexible service entries
