The 3/8" (1/4 NPTF) Female Brass Connector Compression is a must-have for professionals who demand secure, reliable connections. Our Compression Connectors are made with top quality, low-lead brass so they can withstand corrosion from heat, water, and other elements that can cause damage in time. They use an effective fitting - straight adapters - along with a robust sleeve to grab the tubing once tightened with a nut. This provides an incredibly safe seal for both high and low pressure needs, with maximum operating pressure of 200 PSI and temperatures between 40°F and 250°F (maximum). Compression connectors are suitable for high pressure potable water use and are compatible with metals like aluminum, copper or plastic tubing. All in all, our 3/8" Female Brass Connector Compression will provide you with peace of mind knowing that your connections will be safe and secure.
