Series 410 Models 78 and 79 Two-way Shut off Valve Nipple and Coupler

360-Degree Integration

Every unique problem calls for a unique solution. Please contact PCU today to see how we can create a custom designed solution specifically for your manufacturing facility.

Two-way shutoff valved nipples and couplers provide a 1.5 Cv unrestricted flow rate and instant positive connection with a variety of connecting end caps and seal compounds to satisfy your application. Holding pressure from vacuum to 1000 psig, the couplers are repairable with internal parts quickly interchangeable for long life. Use these models when working with a second fluid nearby that must not be mixed. The color and fit difference make it impossible to inadvertently mix with a Model 66 and 67.
