5/16" OD x 1/4" ID Copper Tube Extension



5/16" OD X 1/4" ID copper tube extension.

Use with Sil-phos alloy and copper fittings. Install through the side of the larger line to extend length approximately two inches. Includes a cap (NFT5-4) and valve core.

JB machines all of the access valves at the factory in Aurora, Illinois using the highest level of brass consisting of 65% copper and 35% zinc. This gives our brass fittings and access valves high tensile strength while resisting corrosion. Many import fittings use lower quality brass with lower copper content, resulting in higher failure rates. JB machines all of our valves to the strict guidelines of the ARI to ensure proper sealing of the valve and core surfaces. Our access fittings have generous counter bores to allow for the removal of the core if the flare becomes damaged. All tees and crosses are tapped to receive an access core in all 1/4" SAE flare ends. All pipe connections have internal braze cups for dip tube applications. All valves are equipped with cap and one valve core (braze type, loosely assembled). Temperature range -40 degrees to +250 degrees Fahrenheit (-40 to 121.1 degrees Celsius). Valve core is stainless steel and brass for use with all refrigerants including R-410A. Resistant to oils, alkalites, and diluted mineral acids.

Made in the USA.
