Overview
The Victaulic LPC R20 Style 99 is a replacement gasket seal engineered for use with 5-inch Victaulic Roust-A-Bout Style 99 couplings. Constructed from EPDM and Nitrile elastomers, this gasket provides superior sealing integrity in hydraulic, pneumatic, and general plumbing systems. The gasket is designed to maintain system pressure and prevent leakage in demanding industrial and commercial piping applications.
Key Features
- EPDM/Nitrile Construction — Dual-material composition resists temperature fluctuation and chemical exposure across a wide range of fluid types
- Grade E Gasket Standard — Meets Victaulic specification requirements for Style 99 coupling assemblies
- 5-inch (DN125) Compatibility — Engineered for use with Victaulic plain end and beveled end pipe systems
- Reliable Sealing Performance — Proven elastomer formulation maintains pressure integrity under rated operating conditions
- Easy Installation — Drop-in replacement component requires no special tools or procedures
