PEX Copper Crimping Tool 1/2 in & 3/4 in Combo - Reliable Crimps

Our review of this PEX crimping tool finds it best for plumbers and serious DIYers who need a simple, dependable way to make copper crimp ring connections for 1/2 in and 3/4 in PEX tubing. The single biggest reason to buy is consistency: the tool combines a heavy-duty, chrome-plated jaw with a built-in Go/No-Go gauge so crimps meet the required diameter and the ASTM F1807 standard, helping prevent leaks and rework on installations.

Key Features

• Dual-size capability: Designed to crimp both 1/2 in and 3/4 in copper crimp rings, eliminating the need for separate tools when working with common PEX sizes.
• Chrome-plated jaw: The thick chrome plating resists scratches and impact damage and avoids flaking residue on rings during crimping for cleaner fittings.
• Heat-treated steel construction: Durable jaw and mechanism provide long-term use on jobsite work and repeated crimps without obvious wear.
• Go/No-Go gauge included: The precision gauge verifies proper crimp diameter so connections are secure and meet plumbing reliability checks.
• Ergonomic handles: Cushioned, non-slip grips reduce hand fatigue during repetitive crimping and improve control for tighter crimps.

Who It's For

This tool is aimed at professionals and experienced DIYers who routinely install or repair PEX plumbing and need a compact, reliable crimper for copper crimp rings. It suits jobs where both 1/2 in and 3/4 in sizes are used and where meeting the ASTM F1807 standard is important.

Less experienced homeowners who only do occasional tubing work might prefer a kit with multiple adapters or a more automated crimping tool, since this is a straightforward manual crimper that expects the user to verify crimps with the supplied gauge.

Pros & Cons
