CMP 21063-150-000 1.5" Male Inside Pipe Thread with O-Ring x 1.5" Socket High Temp Union

♨️ High-temperature self-sealing union designed for 1.5" MIP to 1.5" socket (2" spigot) plumbing connections. Ideal for pool, spa, and hot water plumbing where a durable, serviceable joint is required.

• ✅ O-Ring Seal — Built-in O-ring provides a leak-resistant, self-sealing connection without the need for additional gaskets.
• 🔧 Serviceable Union — Allows easy disassembly for maintenance, winterizing, or equipment swaps.
• 📐 Size & Fit — For 1.5" male inside pipe thread (MIP) to 1.5" socket / 2" spigot connections. Confirm pipe type and thread direction before installation.
• ♨️ High Temperature Rated — Intended for applications with elevated water temperatures (pool and spa plumbing). Verify compatibility with your system temperature and chemicals.
• 🔁 Cross-Reference — Commonly interchangeable with comparable high-temp unions; check local part references (example: Praher 150-906) for fit confirmation.

Installation & Use

• 1. Inspect threads and O-ring for damage prior to installation.
• 2. Ensure mating pipe/socket is clean and properly sized; thread engagement should be smooth and straight.
• 3. Hand-tighten the union, then snug with appropriate tools; do not over-torque as this can damage the O-ring or housing.
• 4. After installation, pressurize system and inspect for leaks; retighten if necessary.

Compatibility & Notes

• Designed for use in pool, spa, and general plumbing systems where a removable high-temp union is needed.
• Not all unions are universally compatible — verify thread type (MIP) and socket dimensions before ordering.
• Replace the O-ring if it shows signs of wear, cracking, or distortion to maintain a reliable seal.

⚠️ Safety: Always follow local plumbing codes and manufacturer guidelines. If unsure about fit or materials compatibility with chemicals or temperatures in your system, consult a qualified pool/spa professional.
