Flomasta Shut-Off Valve 15mm (383KR)

Lightweight with a strong grip. A one-step, fully demountable and reusable push-fit plumbing system which combines both push-fit and twist-locking technology to offer a secure leak-free joint which incorporates pressure and combination systems. Twistloc is a twist and lock system suitable for plumbing and local / home hot water supply. Simply push the fitting fully onto the pipe and twist the plastic nut clockwise to lock in place. No special tools are required to fit, just hand-tighten them. Compatible with copper, PB and PEX pipe, making it easy to combine different types of pipe for repairs or new installations. The secure connection indicator is there to ensure a leak-free joint. This is a highly visible green band that is seen when the product is unlocked. Upon connection, this green band disappears indicating that the joint is now properly connected. Will not contaminate the water source, keeping it fit for human consumption.

full bore ?

Hi, are these full bore, want to replace screwdriver type currently installed.
Asked by: pgtips123
Can answer my own Q, I bought 2x and yes they are full bore. Good product, quality is good and consistent size as the screwdriver type isolating valves (the JG Speedfit 15SVP) I was replacing (access was restricted so needed this type of isolation valve as the other was too stiff) so it was a straight swap. Would buy again
