Bushing Plumbing Fittings

Hot Tub PVC Bushing Reducer Fittings for Spa Plumbing

Shop PVC bushing fittings for hot tub plumbing systems. Bushings are reducer fittings used to transition from a larger pipe size to a smaller pipe size inside pumps, heaters, manifolds, and plumbing assemblies.

Available in slip x slip and slip x female threaded configurations.

Proper sizing ensures tight reducer connections and prevents leaks.

Slip vs Street Also Called Spigot

Slip bushings glue inside larger slip fittings.

Street bushings have a male spigot style outer body that inserts into another slip fitting. The outside diameter matches the nominal pipe size.
