Important Notes
- This part is commonly sold as the elbow only. If you also need the sealing O-ring, check your system’s parts list and consider the elbow-with-O-ring version (often listed as SPX1485B6) or replace the union O-ring separately if applicable.
- Always confirm the elbow style and sealing surfaces match your existing union before ordering.
Common Reasons to Replace
- Dripping or seepage at the discharge elbow/union connection
- Cracked elbow body from stress, impact, or freeze damage
- Worn sealing surface that won’t seal consistently (even after replacing the O-ring)
- Damaged connection points that prevent proper alignment
Installation Notes
- Shut off the pump and relieve system pressure before loosening any unions.
- Clean the union sealing surfaces before reassembly.
- If an O-ring is used at the union, inspect it and replace if flattened, cracked, or swollen.
- Use a light coat of pool-safe silicone lubricant on O-rings only (do not use petroleum-based products).
- Hand-tighten union nuts snugly; avoid overtightening plastic fittings.
