A Fabric Roof Leg Sock, also known as a Roof Support Leg Sock or Roof Leg Seal, is a flexible vapour-sealing component installed around the support legs of External Floating Roof Tanks (EFRTs) and Internal Floating Roof Tanks (IFRTs). Its primary function is to minimize hydrocarbon vapour leakage through the annular gap between the floating roof support leg and the roof leg sleeve.

The Fabric Roof Leg Sock consists of flexible polyester fabric coated with polyurethane (PU), securely clamped around the roof support leg and sleeve using stainless steel hose clips. Its flexible construction accommodates floating roof movement while maintaining an effective sealing barrier around the support leg during tank filling and emptying operations.

The sealing arrangement helps minimize hydrocarbon evaporation losses, reduce Volatile Organic Compound (VOC) emissions and prevent the escape of vapours through roof leg openings. For aggressive chemical and special service applications, PTFE-coated fabric can also be selected according to stored product compatibility and operating conditions.
