90411: Flex Adapter with Ball Valve 5/16" female 45° to 1/4" male MASTERCOOL USA 

*Sold by the piece.

The 90411 charging hose, just 10 cm long, with 5/16" female threads at a 45° angle to 1/4" male, equipped with a ball valve, by MASTERCOOL USA, is ideal for R410A and R32 applications, as well as any other systems with 1/4" threads. The built-in ball valve isolation switch prevents the loss of expensive refrigerant and protects the environment.

Mastercool is one of the leading manufacturers of professional-grade charging hoses in North America.

They produce a complete line of refrigerant management products, made from the finest materials and precision-machined to the highest quality standards, meeting the requirements of the American EPA, which mandates shut-off valves within 30 cm of the ends of charging hoses to prevent unnecessary refrigerant venting. Using shut-off valves is far safer than allowing refrigerant to escape during service.

For added flexibility, Mastercool offers accessories sold individually—without hoses—so they can also be used with recycling equipment, flushing units, gauge housings, and more.

At Mastercool, every tool we manufacture is built to last for many years of demanding use!
