Larsen Supply 02-1505 R-42 O-ring 1/2x5/8x1/16 2 Pack

Product Description

The Larsen Supply Co 02-1505 is a No. 21 R-42 O-ring sold in a two-pack, carded format intended for plumbing and fluid-system service work. The ring measures 1/2 inch inside diameter, 5/8 inch outside diameter, and 1/16 inch cross-section, conforming to the R-42 O-ring sizing standard. This profile is commonly used to seal faucet stems, valves, and related plumbing components where a tight, low-pressure static or dynamic seal is required. Plumbers and service technicians keep these on hand for routine faucet repair and valve maintenance calls where quick ring replacement is standard procedure.

This O-ring is suited for residential and light commercial plumbing applications, particularly faucet stem and cartridge repairs, shutoff valve service, and similar water-supply fixture maintenance. The two-pack carded format is designed for counter and peg-display retail or shop inventory. Technicians stocking a service van will find the compact packaging practical for organized parts storage.
