Produced in high performance thermoplastic udel® Polysulfone, these 3/8″flow size couplings are more durable and stable at higher temperatures. The 60PS Series couplings offer a new and improved Panel Mount design that has a more reliable, thumb-latch which makes it more durable,easier and faster to use. All 60PS couplings interconnect with all other 60 Series couplings as well as other similar industry thumb-latch type high flow couplings
