DOT push in fittings (DOT push to connect fittings) are constructed with an all brass captive eyelet which allows for maximum flow. The brass captive eyelet with extended length is floating and has a machined top end radius for easy instal-lation of tubing. All male threads of the DOT push in fittings (DOT push to connect fittings) have a pre-applied Teflon based pipe sealant to provide for easy assembly and leak proof seal.
