Larsen Supply Co. 02-1455 Number 9 O-ring 2 Pack

Product Description

The Larsen Supply Co. 02-1455 is a Number 9 O-ring sold in a two-pack, carded for easy retail or shop storage. This O-ring measures 5/16 inches ID by 1/2 inches OD by 3/32 inches cross-section and is used to create a leak-free seal at threaded connections, valve stems, and fittings in plumbing and HVAC systems. Licensed plumbers and service technicians keep standard-size O-rings on hand for quick repairs during service calls, reducing callbacks caused by dripping connections or weeping valve bodies.

The Number 9 O-ring is a common size used in residential and light commercial plumbing repair, faucet rebuilds, valve stem service, and related fixture work. The carded two-pack format is suited for counter display in supply houses or for stocking a service van with frequently replaced sealing components.

Installation Notes

Installation is typically performed by a licensed plumber or experienced service technician. Shut off the water supply and relieve system pressure before disassembling any valve or fitting. Inspect the seating surface for scoring or corrosion before installing the new O-ring, and lubricate the O-ring with a compatible plumber's grease to ease installation and extend seal life. Follow applicable local plumbing codes, including IPC guidelines, when performing valve or fixture service.
