Size:1/4′ Flow Coupler x 1/4′ Barb This Colder tube fitting is made of natural white acetal copolymer plastic, mounts on a wall or panel, and connects tubing to a Colder PMC series coupling through a barrier. This coupler has a barbed fitting on one end to create a tight seal on flexible and semi-rigid tubing when used with a hose clamp or crimp sleeve or ferrule (sold separately). A female Colder PMC series 1/8 flow coupling on the other end has a stainless steel thumb latch for quick release. The valve spring is made of type 316 stainless steel that resists corrosion. Acetal copolymer plastics have low moisture absorption, high tensile and flexural strength, and are resistant to fatigue. The coupling has a temperature range of -40 to 180 degrees F (-40 to 82 degrees C), and supports working pressure to 120 psi (8.3 bar). Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness). Colder Products Company manufactures quick-connect couplings, fittings, and connectors for plastic tubing. The company, founded in 1978, is headquartered in St. Paul, MN.
