Roxtec RS PPS/S F+WT AISI WOC
Built for the harshest environments, the Roxtec RS PPS/S F+WT AISI 316 WOC is a heavy duty, maringrade penetration seal engineered to route a single plastic pipe safely through circular openings in walls, floors, decks, and ship bulkheads.

Where fire and water pose the greatest risk, this seal delivers. Its back-to-back-to-back arrangement with built-in intumescent material expands under heat, maintaining certified fire protection and long-term water tightness—even after direct fire exposure. Crucially, the seal features no solid centre core plug, making it designed exclusively to wrap directly around an active, continuous pipe during installation. No interruptions. No system shutdowns.

Manufactured from AISI 316 stainless steel, it withstands the relentless corrosion and extreme conditions common to marine and offshore settings. It is a trusted solution across a range of demanding industries, including marine and shipbuilding, offshore oil and gas, and industrial and heavy infrastructure.

When the integrity of your vessel, platform, or facility depends on a single seal, the Roxtec RS PPS/S F+WT AISI 316 WOC is built to hold the line.
