Lokring l13000679 Tube Fitting 0.354 to 0.313 Inch

Product Description

The LOKRING l13000679 is a solderless tube fitting designed to join or repair refrigerant and fluid lines in HVAC and appliance applications. Designated as a 9/8 NR MS 00 connector, this fitting accommodates tubing with an outer diameter of 0.354 inches on one end and 0.313 inches (5/16 inch) on the other, making it a reducing-style connector. LOKRING fittings use a mechanical compression method that eliminates the need for torches, solder, or brazing equipment, which reduces fire risk and speeds up field repairs. Licensed HVAC technicians and appliance service technicians are the primary installers of this fitting.

This fitting is suited for use in residential and light commercial HVAC systems as well as refrigerating appliances where refrigerant line repairs or modifications are required. It is particularly useful in situations where open-flame brazing is restricted, impractical, or prohibited by site conditions. The reducing configuration allows technicians to transition between two common tubing sizes without fabricating custom adapters or splices.
