Product Introduction

The airtight gland passes a power, control or data cable through an enclosure or cleanroom panel without leaving an annular air path. Tightening the cap compresses an elastomer insert uniformly around the cable jacket while a second gasket seals the gland body to the mounting surface. The external profile is rounded and compact, with no split threads exposed to the cleaning area.

Key Features

A circumferential insert seals directly against the cable outer sheath.

The body-to-panel washer closes the penetration independently of cable compression.

Strain relief transfers pull load away from internal terminals.

A smooth rounded cap supports direct wiping around the entry point.

Different inserts accommodate single cables, multiple small cables or conduit tails.

Customer Product Concerns

A cable entry can leak either around the cable or around the gland body, so both sealing interfaces must be controlled.

Air leaks through the gap between cable and drilled hole.The compressed elastomer insert closes uniformly around the cable sheath.

The gland rotates and breaks the panel seal during tightening.A locknut or keyed body retains the gland while the cap is torqued.

Cable movement transfers force to delicate terminals.Integrated strain relief grips the outer jacket before the connection point.

Several small cables require multiple wall penetrations.A multi-hole sealing insert groups compatible cables in one gland body.
