Hex hole screw on cap. Orange (or white) body held with metal washer and nut - o ring seal on bottom, with a screw on elbow adaptor. Generally the caps corrode away and the metal washer rusts, causing the fitting to crack and leak. Fit a 19mm hole size. (metal washer missing from injector pictured)
Replace with either Waterway LoPro or Oz Air Injectors listed above - the only 2 air injectors available to suit the hole size used by In-Spa-Ration. All air injectors, the air hose and manifold will also require replacement due to size. In-Spa-Ration used 1/2" or 13mm white hose marked with the words In-Spa-Ration stamped along it. Manifold also 1/2" barbs. All air injectors available for outdoor spas available today are for 3/8" or 9mm barb/hose. The back of the jet body is also marked 'in-SPA-ration'
