Cleanroom Wall Sleeve
A double-flange stainless steel sleeve that forms a smooth, durable passage through cleanroom wall panels for pipes and services.
- Smooth Hollow Bore
- Double Hygienic Flange
- 304 Stainless Steel
- Panel-Edge Protection
Product Introduction
The cleanroom wall sleeve is a rigid stainless tube with broad circular trim flanges at both ends. Installed through a prepared panel opening, it protects the exposed panel core and creates a smooth bore for routing a process pipe, conduit or service line. Continuous welded transitions and brushed surfaces simplify perimeter sealing and wipe-down on both room faces.
Key Features
Two broad flanges cover the cut edges on both sides of the partition.
Smooth welded tube-to-flange transitions reduce dirt-catching ledges.
Sleeve diameter and barrel length can be matched to the service and panel thickness.
Customer Product Concerns
A raw hole through an insulated cleanroom panel exposes core material and leaves an irregular perimeter that is difficult to seal and clean.
Cut panel edges release debris or absorb moisture around the penetration.The continuous metal barrel isolates the panel core from the service passage.
Irregular openings leave visible gaps around the pipe route.Broad end flanges cover the cut perimeter and provide consistent sealing faces.
Sharp panel skins can damage cables or small tubing.The smooth finished bore removes exposed sheet-metal edges from the passage.
Fixed stock lengths do not match different wall build-ups.Sleeve length is produced to suit the panel thickness and finish allowance.
Typical Applications
Process-pipe wall passagesClean utility conduitsElectrical service penetrationsInstrument tubing routesHygienic panel openings
