How to choose the right part
Before ordering, inspect the old part and compare its shape with the photos. The manufacturer's number is given above and is the surest way not to make a mistake. It is a good idea to replace the worn part at the very start of the season, before you run the filtration at full speed. This way you avoid a shutdown in mid-summer and a more expensive repair. If you have any doubts, contact us and we will help you.
How to install the Krystal hose adapter
First switch off the pump and release the pressure in the filter. Then unscrew the old adapter and clean the thread. Screw on the new adapter by hand. Put the hose over the nozzle and tighten the clip. Finally, start the filtration and check for leaks.
Why choose an original part
The adapter has the same thread as the Krystal valve. That is why it fits exactly and does not let air in. Also, the clip makes the connection secure without extra tools. The original part is a better choice than universal adapters, which often work loose.
Care and storage
After every winterisation of the pool, wash the parts with cold water and let them dry. Store them dry, away from chemicals. This way the rubber and plastic parts stay in good condition until the next season.

Not sure this is your part?
Send us the model of the unit and a photo of the old part. We will check compatibility before you order.
