Cap Diameter of 100mm. Originally came in grey, white and in notched or scalloped tops. Common diverter parts for many older spas. This is the Non-Buttress style that suited Monarch and many other brands in the late 1990s and early 2000s. Very common on Australian-made spas from the early 2000s, from Signature, Spa Industries, and Monarch Spas. On Spa Industries made spas, they often had a "Jet Selector" label on them. 

These have a V-shaped thread on the body. If you have a similar-looking Buttress-threaded diverter, you will need parts for a different (Waterway) diverter.

Parts Available:

• Complete Repair Kit
• Cap (approx 100mm Diameter)
• Handle
• O-ring Seal Set
• Internal Rotor / Gate

Important Notes: There are similar parts to these. In order for these to fit, your Cap must *not* have the word "Buttress" printed underneath. See below photo to double-check the thread on your diverter body.

Non-Buttress "V-Shape" thread is used on older spas, including many older Signature, Spa Industries, and Monarch Spas. "Buttress" is a later type of thread used.
