Larsen Supply Co. 02-1513 R-46 O-ring 5-1/4x3/8x1/16 2 Pack

Product Description

The LARSEN SUPPLY CO., INC. 02-1513 is an R-46 O-ring sold in a 2-pack carded format for trade and maintenance use. It measures 5-1/4 inches in outer diameter, 3/8 inches in cross-section width, and 1/16 inches in cross-section thickness. O-rings of this type create a reliable pressure seal at joint connections in plumbing, HVAC, and fluid-handling systems. Plumbers, pipefitters, and service technicians install these to prevent leaks at fittings, valves, and threaded connections. The carded 2-pack format makes it easy to stock and carry in a service kit or van inventory for quick field repairs.

This O-ring is suited for residential and light commercial plumbing and HVAC service applications where an R-46 size seal is required. It is commonly used during routine maintenance, valve rebuilds, and fitting replacements. The compact size and standard R-46 designation allow service techs to quickly cross-reference and confirm fitment at the point of repair. Each pack contains two rings, providing a backup on hand during a single service call.

Installation Notes

O-ring replacement is typically performed by a licensed plumber or HVAC technician. Shut off the water supply or isolate the refrigerant circuit and relieve system pressure before disassembling any fitting or valve. Inspect the seating surface for nicks or corrosion that could compromise the new seal. Do not over-stretch the O-ring during installation, as deformation will reduce sealing performance.
