Waterproof rigid stainless steel pipe sleeves for building concrete walls
Application of pipe sleeves
When passing steel, cast iron, copper or plastic pipes through walls, ceilings or floors, waterproof sleeves serve as a protective conduit. The pipe passes through the inside of the sleeve.
Stainless steel pipe sleeve benefits
- Save time and money for civil works
- Positive hydrostatic sealing
- Long seal life
- Seals and pipe
- Corrosion protection
- Compensates for misalignment
- Absorbs shocks, sound and vibration
