ARG 1.5" Union 1.5" MPT x 1.5" Socket (Male Thread)
Standard 1.5" union with 1.5" male pipe thread x 1.5" socket. O-ringed face and service nut for quick equipment disconnects. SKU UMT015.
Features
- 1.5" MPT x 1.5" socket for common pump/heater/filter ports.
- O-ringed union face—no sealant needed at the joint.
- Hand-tight service nut for fast maintenance.
Description
Thread the union onto the equipment port, glue the 1.5" socket to your PVC line, and tighten the nut to compress the O-ring. You get a durable, reusable seal that simplifies future service—no cutting or re-plumbing.
Pro Tip
Apply a thin film of silicone O-ring lubricant and align straight before tightening to avoid pinching the gasket.
Installation Tips
Use PTFE tape or approved thread sealant on the 1.5" MPT side only. Prime and cement the socket per PVC instructions. Hand-tighten the union nut; do not over-torque. Keep the O-ring clean and lightly lubricated.
