Island Spas Plumbing Parts — Match by Size & Connection

Manifolds, barbed fittings, elbows, couplings, pump unions, and flex hose for Island Spas live here, matched by nominal pipe size and connection type — slip (smooth glue socket), spigot (fits inside a slip socket), or barb (pushes into flex hose). One honest measuring note: spa plumbing uses nominal sizing, so “2 inch” pipe measures larger than 2 inches across the outside — compare your part’s ports to the listed dimensions, and when in doubt, the tape-measure photo settles it.

Island Spas Plumbing Parts FAQs

Right here — this category carries Island Spas manifolds, fittings, unions, and hose, with more added as we expand the catalog. If the fitting you need isn’t listed yet, send a photo with your serial number through the form; we stock far more than what’s currently online.

Photograph the part next to a tape measure showing the port openings, and note the connection style: slip sockets are smooth and glued over pipe, spigots insert into slip sockets, barbs push into flex hose with clamps. Nominal sizes run larger than their name across the outside — which is why we ask for the tape in the photo.

Rigid schedule 40 fittings in standard sizes often cross over, but spa-specific parts — flex hose, barbed manifolds, pump unions with gaskets — don’t have true hardware-store equivalents. Match the spa part and you avoid the adapter-stack that becomes tomorrow’s leak.

✅ Not Sure Which Fitting Fits? Verify Before Ordering
