Spa Air control kits to replace various air controls that are no longer available in spas and hot tubs. Choose number of ports. Only comes in Grey. Suits 41-50mm hole in spa top.

Smaller holes can be reamed out using something like an "Oops Arbor" style hole saw with stepped thread, or with a die grinder bit. 

Kits Come With:

• Grey Top Draw Air Control
• Air Tubing (10mm 3/8") - approx 200mm Air Tubing Per Barb (eg: 2-port kit comes with 400mm air tubing, 6-port kit comes with 1.2m tubing)
• Air Tubing Joiners
• Air Manifold/s - Each kit comes with a plug to block off unused barbed nipple.

Tips:

• Heat old/new tubing gently with a heat gun or small torch (don't burn it) to make pushing barbs into much easier.
• Use PVC glue on male side of barbs only (no clamps needed)
• Standard 25mm pressure pipe and fittings can be used to make manifolds go at angles if there isn't enough verticle space.
