No more stuck or perished washers with new drain off cocks

Plumbing and heating engineers have continual issues with stuck, jammed or failed washers within drain off cocks, which can potentially cause delays and damage to properties. This is where neXgen says it has the solution with a better design that means no more stuck or perished washers.

The neXgen drain off cock is suitable for draining hot and cold water, heating system water, and glycol/antifreeze from a solar system. The company claims that its patented, one-piece insert is a complete overhaul on the traditional and outdated design which has serviced the country for many years.

The one-piece inner moves in and out of the body and doesn’t rely on spindles, washers or fiddly moving parts that are subjected to debris and corrosion over the years. The acetal inner is low-friction and made from high-wear resistance material, with high strength and stiffness properties. It also provides a wide operating temperature range (-40 °C to 120 °C), suiting it to a wide range of applications.

Available in three different variations: the standard 15mm for solder and compression; the long tail version for press fit, push fit, solder and compression; and the premium version, which is suitable for all these applications but has the added benefit of the hozelock connection.

Code Description Suitable for applications
NEXGENS neXgen Standard 15mm DOC Solder and Compression
NEXGENL neXgen Long tail 15mm DOC Press fit, Push fit, Solder and Compression
NEXGENP neXgen Premium 15mm DOC Press fit, Push fit, Solder and Compression

The hozelock connection on the premium DOC enables quick connection with a hose pipe when attempting to drain down the system, but it is also an ideal connection for engineers looking to fill or flush the system.

The product range was released in June 2022, with neXgen saying it has been received positively by installers and that it is being rolled out to all good merchants and stockists.
