Larsen Supply Co. 0-3013 Ptfe O-ring Set Faucet RP25

Product Description

The LARSEN SUPPLY CO., INC. 0-3013 is a PTFE-coated O-ring set designed for Delta single-lever lavatory and kitchen faucets in both old and new style configurations. Each set includes four O-rings and is packaged one set per card. The PTFE coating reduces friction and helps the O-rings resist wear, chemical degradation, and leaking over time. This is a direct OEM-referenced replacement part, referenced against Delta part RP25, making it a reliable choice for plumbers and fixture repair technicians servicing Delta faucets in the field.

This O-ring set is suited for residential lavatory and kitchen faucet repairs where the original Delta single-lever cartridge or valve body seals have worn, cracked, or begun leaking. It covers both older and current Delta single-lever designs, making it useful for service calls on a wide range of faucet vintages. Plumbers performing routine drip repairs or full cartridge rebuilds will find this kit addresses the most common seal failure points in these fixtures.

Installation Notes

Installation is performed by a licensed plumber or qualified fixture repair technician. Shut off the water supply valves under the sink before disassembling the faucet. Relieve line pressure by opening the faucet handle fully before removing the cartridge or valve body. Inspect the O-ring seats for scoring or debris before seating the new O-rings to ensure a proper seal.
