Plumbing sizes can be confusing. Pressure PVC pipe use nominal sizes - the size is simple a name, not the measured dimension. This convention is used across most pool and spa systems so that pipes and fittings remain compatible.

• 50mm / 2" = ~60-61mm OD
• 40mm / 1.5" = ~48mm OD
• 25mm / 1" = ~33-34mm OD

Common plug types found on spa equipment are AMP, Mini JJ, C38 (Aus 3-pin), Gecko in.link, etc. For more information please click here.

• AMP plugs are the most common type used for over 20 years.
• Many Mini J&J plugs are no longer available and must be modified.
