SUR-R Flared Fitting Nut: 3/16 in OD Fitting Size, Flared, 3/8"-24 Thread Size A

A SUR-R flared fitting nut creates a leak-proof seal in industrial tubing systems by compressing a flared tube end against a mating cone. It is commonly used in hydraulic, pneumatic, and instrumentation lines where vibration resistance and reliable connections are required.

The SUR-R BR135 is a standard steel inverted flare tube fitting nut with a 3/16 in OD fitting size and a 3/8"-24 thread size A. It comes in a 4-pack and provides a flared connection type for industrial tubing systems.

To install a SUR-R inverted flare fitting nut, first cut the tubing square and deburr the end. Slide the nut onto the tube, then use a flaring tool to create a 45° flare. Tighten the nut onto the mating fitting with a wrench until snug—avoid over-tightening to prevent damage.
