Caps & Plugs Plumbing Fittings
Hot Tub PVC Caps and Plugs for Spa Plumbing Repair and Winterizing
Shop PVC caps and plugs for hot tub plumbing systems. Caps are used to seal the end of pipe, while plugs seal the inside of threaded or slip fittings. These are commonly used during spa winterizing, pressure testing, and plumbing modifications.
Proper sizing ensures a watertight seal and prevents leaks.
Slip vs Street Also Called Spigot
Slip caps glue over the outside of pipe.
Threaded plugs screw into female threaded fittings.
Street style caps insert into slip fittings with a male spigot style end.
How to Measure Spa Plumbing
Measure outside diameter of pipe before ordering caps.
Measure inside diameter of fitting before ordering plugs.
