PPA Series Couplings are general purpose, 1/4" body size, thermoplastic quick couplings. The push-to-connect feature and push-button release provides quick and easy operation. An audible "click" confirms the connection has been made. These smooth operating couplings, with all plastic latch, are highly resistant to accidental disconnect. The couplers and nipples are available with or without valves. Standard seal material is nitrile and bodies and latches are acetal copolymer with stainless steel springs. PPA couplers have a fully plastic exterior and smooth face, making them non-marring to most surfaces. The PPA series couplings are resistant to many chemicals, and are suitable for liquid and gas applications. They have a flow capacity of 1/4". Couplings will withstanding temperatures between -40°F to 180°F, and are rated for vacuum to 120 psig. Applications include medical devices, laboratory equipment, chemical processing, food and beverage, industrial and process equipment. Note: PPA series does not interchange with PPL or PPM series.
