Insert Fittings

Insert Fittings

We offer a variety of insert fittings in PVC, polypropylene and steel – all designed to connect flexible polyethylene plastic tubing using either clamps or compression fittings. Because polyethylene plastic tubing comes in long coils and requires support every 32" (and is subject to kinking if bent too far), using our insert fittings vastly simplifies the installation of flexible plastic tubing and hosing systems. Special Note: Recommended for coldwater applications (as is all polyethylene plastic tubing).
