Thin walled press-fit fittings are made of a precision deformable body, containing an O-ring (elastomer) seal as well as a mechanical grip ring. Thin-walled precision tube is pushed into the fitting, and then a specially designed press-fit jaw, or crimping tool is used to compress the fitting body, seal and grip ring onto the tube, thereby creating the joint.
Thin walled press-fit fittings provide a permanent, heat-free jointing installation. These systems are sometimes referred to as crimped or socket fittings. These systems are designed to work with thin-walled precision tubes. Different O-ring (elastomer) materials may be used for different applications.
Typically, these fittings are typically manufactured from carbon steel, stainless steel, and copper. A chrome plated finish can be found on copper variants for functionality and maximum aesthetic appeal, for example in bathrooms and kitchens.
