CMP 2 in Self-Aligning Union 2 in Socket x 2 in Socket 21049-200-000

Tired of cutting pipe every time a pump or filter has to come out? This CMP self-aligning union makes the joint serviceable — unthread the nut and the equipment lifts free — and the self-aligning design forgives slight pipe misalignment that makes standard unions cross-thread and weep. A complete union with nut, tailpieces, and O-ring seal.

🚩 PRO TIP: Hand-tighten only, and put a dab of silicone lubricant on the O-ring — never Teflon tape on union threads. The O-ring makes the seal; the nut just holds it, and over-tightening cracks nuts.

FREQUENTLY ASKED QUESTIONS:

• What does self-aligning mean? The sealing faces can float slightly, so the union seals squarely even when the two pipes are not in perfect alignment — the most common cause of union drips on equipment pads.
• Is the O-ring included? Yes — this is the complete union assembly with nut, both tailpieces, and the O-ring seal.
• Where is it used? Anywhere a 2 in pool line needs a removable joint — pump, filter, heater, and chlorinator connections on in-ground and above-ground systems.
