Do I need any additional parts for installation?
To install a Pureline PL1792 housing assembly, you’ll need a few additional parts beyond what comes in the box. The housing itself includes the impeller and unions, but it is not a complete pump, so key components must be added.
You may also need:
- Standard Shaft Seal – PS-201 or Saltwater Shaft Seal – PS-3868
- Teflon tape or thread sealant
- Compatible unions (Pureline Pump Union, 2″ Male x 2″ Slip, Single | By Pureline | PL1647)
For saltwater pools, a salt-rated shaft seal is recommended for longer lifespan.
Is the PL1792 an OEM (original) part?
No. The PL1792 is an aftermarket replacement part, meaning it is not made by Hayward but is designed to the exact specifications of Hayward’s Super II design.
