CMP 21063-750-000 3/4" MIP X 3/4" S UNION S-S HI-TEMP

🔧 Durable high-temperature 3/4" plumbing union designed to join a 3/4" male threaded connection to a 3/4" slip/link fitting in pool and spa circulation systems.

• ✅ Purpose: Creates a secure, serviceable connection between threaded and slip plumbing without having to cut or glue pipes.
• ♨️ High-temperature construction: Built to withstand elevated water temperatures commonly found in hot tubs and spa equipment.
• 🛠️ Material: Corrosion-resistant stainless steel (stainless finish) for long-lasting performance in wet environments.
• 📐 Size & compatibility: Connects 3/4" male iron pipe (MIP) thread to a 3/4" slip/socket fitting. Works with standard 3/4" pool/spa plumbing components and threaded adapters.

Features & benefits

• Tool-friendly union nut for easy assembly and disassembly during service or equipment replacement.
• High-temperature rating helps protect seals and body from heat-related stress in spa and heater applications.
• Stainless construction reduces corrosion and extends working life compared with non-metal unions.

Installation & usage

• Before installation, inspect sealing surfaces and apply an appropriate thread sealant or tape to MIP threads as recommended by the plumbing or equipment manufacturer.
• Bring faces together and hand-tighten the union nut until snug; finish with a short wrench turn if necessary to ensure a leak-free seal. Avoid over-tightening to prevent damage to threads or seals.
• After installation, pressurize the system and check for leaks; re-tighten or re-seat seals if needed.

Who this is for

Ideal for pool and spa technicians, service professionals, and DIYers replacing or servicing pumps, heaters, or inline equipment where a removable 3/4" threaded-to-slip connection is required.

Note: Verify compatibility with your specific equipment and pipe types before ordering. Refer to your equipment manual for recommended sealants and installation torque.
