Design Meets Technology

With advanced thermoplastic material for extreme conditions, and connecting to copper, PEX and CPVC, JG ProLock is the most durable, versatile fitting on the market. ProLock does everything you’d expect from a quick-connect fitting – but it’s the things you might not expect that have changed the way plumbers do business:

• Works with copper, PEX, and CPVC
• Code-approved in Canada and the US
• Approved for behind-wall use
• No tools required for installation or removal

Still, it takes more than word of mouth (or an email) to earn your trust. So we remain committed to shipping free sample couplers to professionals looking to stay on the cutting edge. Try it once, and imagine the difference ProLock could make.

Sincerely,
John Guest
