Somewhat thorough reworking of the entire thing ;)
Adapters to suit inlet/outlet of Intex/Bestway pools.
The inlet/outlet fittings for these pools come in two flavours, there are the "small" ones which "push fit" on the smaller pools, then there are the "large" ones which pass through the wall of the pool and have a nut on the back to secure them (the pictures may help).
The "large" strainer adapters have two threads on them, there is an "inner" thread which matches the dimensions of the "small" strainer adapters (though strainers for the "small" adapters will not fit out of the box because there is an integral strainer), I've designed adapters which will couple to either thread.
The adapters consist of multiple parts, for the "small" strainer adapters (or the inner thread on the large adapters) they are in two parts, there is the threaded "ring" then there is an "adapter" which mates to the ring to connect whatever it is you actually want to connect.
The "large" adapter is a threaded ring, and an 'adapter plate' which allows it to use the adapters used by the "small" rings (again, consult the photos).
- Ring_Large_Inner - threads onto the "inner" thread on the "large" strainer adapters, mates to one of the adapters below.
- Ring_Large_Outer - threads onto the "outer" thread on the "large" strainer adapters, in combination with the "adapter plate" below mates to one of the adapters listed below.
- Ring_Small - threads onto the "small" strainer adapters, mates to one of the adapters below.
- Large_Adapter_Plate - allows connection between a "ring_large_outer" and one of the adapters below.
Adapters (note there are no retention features on the "hose" connections, so they are probably only suitable for suction):
- Adapter_32_Cuff - should mate with the cuffs on most "standard" pool accessory hoses.
- Adapter_32_PVC - the ID of this adapter will mate to the OD of 32mm PVC pressure pipe.
- Adapter_32mm_Hose - mates to the 32mm/1-1/4" push-on hoses which are supplied with smaller pools and the "Deluxe Pool Maintenance Kit"
- Adapter_38mm_Hose - mates to the 38mm/1-1/2" push-on hose which is supplied with the surface skimmer.
- Adapter_Solid - "blank" adapter with no hole.
If you want to design your own adapters for use with the "rings" (or the adapter plate) you need a step ~82.6mm diameter (the rebate is 83.5mm diameter, and you need a bit of clearance for glue) and 3mm deep on the bottom of your adapter to mate to the ring.
