Overview
The Victaulic LPC R20 3″ grooved coupling gasket is a fire protection sealing component engineered for use in grooved pipe coupling assemblies. The LPC R20 gasket works in conjunction with coupling housings and bolts to create a mechanical pipe joint suitable for fire protection sprinkler systems and industrial plumbing applications requiring Loss Prevention Certification Board (LPC) approval. Constructed to stringent standards, this gasket ensures full circumferential engagement within grooved couplings, delivering consistent sealing performance across thermal cycles and pressure variations.
