Addaptor angle 90° 1/4" 90333-R shut off valve MASTERCOOL USA 

The 90° angle, 90333-R, shut off valve with 1/4FL.M x 1/4FL.F threads easily connects to any transfer hose and converts it for reliable operation with a built-in shut off automatic isolation switch (shut off valve), preventing the loss of expensive coolant and protecting the environment.

Mastercool is one of the leading manufacturers of professional quality "auxiliary accessories" in the American continent.

It manufactures a complete line of shut-off valves for refrigerant limitation, so the adapters are made of the best materials and precision machined according to the highest quality standards, meeting the requirements of the American EPA which requires shut-off valves within 30cm of the ends of the transfer pipe to avoid unnecessary refrigerant venting. 

Using shut off valves is much safer than letting the coolant escape during service. For flexibility, Mastercool offers shut off valves individually, without the hoses, so they can also be used in recycling equipment, flushing equipment, gauge housings, etc.

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