Make a tool-free transition from 1/2" copper tube size (CTS) plastic tubing to a 1/2" male pipe thread with this Type 01 polysulfone push-fit fitting. Insert the tubing, give it a tug to seat the grab ring, and you have a sealed connection rated for hot or cold supply lines - no clamps, no crimping, no soldering.

• 1/2" CTS push-fit inlet x 1/2" MPT (male pipe thread) outlet
• Tan polysulfone body - brass-free, lead-free, and dishwasher-safe materials of construction
• Compatible with PEX, CPVC, polybutylene (PB / Qest), and copper tubing in 1/2" CTS sizing
• Internal grab ring and EPDM o-ring seal grip and seal the pipe in one motion
• Removable with a release collar - reuse the fitting after disassembly
• Suitable for potable water, hot and cold supply lines, and ice maker / refrigerator hookups
• 1 per poly bag

Best for: repairing or extending polybutylene supply lines, transitioning PEX or CPVC to threaded valves and fixtures, and emergency repairs where you can't sweat copper.

Tip: Cut the tubing square with a tubing cutter (not a hacksaw), deburr the inside and outside edges, and push the tube in until it bottoms out - then pull gently to confirm the grab ring has set.
