Product Description

The LARSEN SUPPLY CO., INC. 11-1027 is a 0.5 oz silicone lubricant formulated for faucet stem applications in residential and commercial plumbing systems.

Installation Notes

Applied by licensed plumbers during faucet service and repair. Shut off the water supply at the fixture stop valve or main before disassembling any faucet components. Apply a thin, even coat to stem threads, O-rings, and packing surfaces before reassembly. Avoid over-application, which can attract debris and accelerate wear on sealing surfaces.
