Roxtec SLRS 31 PRIMED

When a single cable or pipe needs to pass cleanly through a wall, bulkhead, floor, or deck, the Roxtec SLRS 31 PRIMED gives engineers exactly what they need, -a precision-engineered cylindrical metal sleeve purpose built to house and secure a Roxtec RS series round entry seal.

The sleeve creates a perfectly sized, stable housing cavity that allows the round rubber RS seal to expand into a high pressure mechanical fit, no gaps, no guesswork. When paired with the correct entry seal, the completed assembly achieves certification for A-class fire protection, gas tightness under catastrophic pressure, and resistance to water ingress. That level of protection matters most where the stakes are highest: aboard marine vessels, on offshore oil and gas platforms, inside cleanrooms, and throughout heavy industrial processing plants.

Constructed from mild steel and finished with a base primer layer, the SLRS 31 PRIMED arrives ready to weld and coat. Once installed, it can be painted or finished to match the surrounding structure, keeping penetration points both structurally sound and visually consistent with the rest of the build.
