Description
Balboa 1 1/2" Slip x 1 1/2" FIP Union Assembly (11-3550)
Introducing the Balboa 1 1/2" Slip x 1 1/2" FIP Union Assembly (11-3550) — a purpose-built, OEM-grade connection from Balboa Water Group (BWG) designed to simplify spa plumbing in hot tubs and whirlpool baths. This complete union fitting bridges a 1-1/2" slip pipe with a 1-1/2" FIP (Female Iron Pipe) threaded port, delivering a secure, serviceable link for Balboa-powered systems.
Key benefits that matter in real-world spa projects
- Two-connection versatility: one end accepts 1-1/2" slip piping, the other end threads as 1-1/2" FIP, enabling flexible integration with both solvent-welded runs and threaded spa components.
- OEM-grade reliability: built to match Balboa’s standards for pumps, heaters, controls, jets, and accessories, ensuring consistent performance within the BWG ecosystem.
- Service-friendly design: the union configuration allows quick disassembly for component replacement or routine maintenance without re-plumbing the entire loop.
- Inventory-friendly sizing: standard 1-1/2" connections reduce the need for adapters, simplifying repairs and stocking.
Ideal applications
This union assembly is perfect for connections where a 1-1/2" slip line meets a 1-1/2" FIP threaded port. Use cases include attaching spa pumps to heaters, linking control-system manifolds, or replacing aging unions in Balboa-powered spas. If your system relies on Balboa components, this 11-3550 fitting ensures compatibility and straightforward servicing.
Installation tips
- Prepare and verify: ensure pipe ends are clean and properly aligned before assembly.
- Threaded side: apply appropriate thread sealant or Teflon tape on the FIP threads per component manufacturer guidance, then tighten by hand and finish with a snug final turn. Avoid overtightening to prevent damage.
- Slip side: slide the slip end onto the 1-1/2" pipe and tighten the union nut to achieve a tight, leak-resistant joint.
- Test for leaks: after installation, run the system at low flow to confirm a secure seal and re-tighten if any moisture appears.
