Why Choose 1/2″ PVC Compression Coupling?
Easy Installation – No Solvent Needed
The UCC01 coupling allows quick connections without primer or glue. Your installation crew can tighten the nuts to form a seal, reducing labor time and mess.
Ideal for Repair & Maintenance
Perfect for repairing leaks or modifying existing pipeline systems—just loosen, remove, and reassemble without damaging pipe. Great for irrigation, garden systems, or potable water repair.
Flexible & Reusable
Unlike glued fittings, 1 2 pvc compression couplings are reusable. This makes them cost-effective for systems that may need future reconfiguration or maintenance.
Reliable Performance
With a solid rating of up to 200 PSI (depending on model) and a durable gasket material (EPDM / Buna-N), this coupling stands up to plumbing demands. Many competing products from top brands emphasize similar pressure capabilities.
How to Install the UCC01 1/2 PV Compression Coupling
1. Prepare the pipe
Cut pipe cleanly and squarely.
Deburr inside and outside edges.
2. Slide on the Compression Nut
Slide the nut over the pipe; then follow with the gasket.
3. Insert into Body
Push the pipe into the coupling body firmly until it bottoms out on the gasket.
4. Tighten Nuts
Hand-tighten the nuts first, then use a wrench to finish. Do not over-tighten, as this may deform the gasket.
5. Secure the Assembly
Because compression joints don't restrain against thrust under pressure, support or block the piping to avoid movement under load.
