Buying Guide
Key purchase considerations help you select the right 1-1/2″ pool fittings.
- Compatibility: Check hose diameter, thread type (NPT vs FIP), and model compatibility (Hayward SPX1091Z7/SPX1091Z4, skimmers, feeders).
- Material and durability: PVC profiles offer corrosion resistance; EPDM O-rings improve sealing under chemical exposure.
- Installation ease: Look for included sealants, tape, or simple screw-on unions to minimize leaks and time.
- Application fit: Use best-for statements (best for above-ground pumps, best for PVC plumbing, best for mixed hose sizes) to align with your setup.
