Push-to-Connect Fittings
Push-to-Connect fittings enable quick tubing connection and disconnection. A variety of Male and Female Connectors, Elbows and Tees feature tube ODs ranging from 1/8 to 3/8 and 10-32, 1/8 NPT or ¼ NPT threads. To ensure a leakproof fit, thread sealant is standard on all male pipe threads and the 10-32 UNF thread features an o-ring for a superior seal.
