DIG swivel fittings are used for quick assembly of manifold valves or as a union in a valve or filter installation. DIG swivel fittings are available in 1", 1 1/2" and 2" configurations, are constructed of high impact UV resistant plastic, and are highly chemical resistant. DIG swivel fittings use a large swivel (FNPT) with an encapsulated nitric rubber O-ring to allow quick and easy tightening without tools or Teflon tape.
DIG high-pressure polypropylene swivel fittings are designed for ease of assembly, repair and addition of valves without glue, pipe tape, teflon tape or special tools.
