Product Description

This John Guest union straight connector fitting is made of acetal copolymer and has tube connectors. This union straight connector fitting is for connecting and disconnecting two inline pipes more easily than using couplings. It is a push-to-connect fitting that accepts the insertion of nylon, soft nylon and polyurethane tube fittings. It is made of acetal copolymer plastic, which has low moisture absorption, high tensile and flexural strength, and is hard and fatigue resistant. The working pressure for this fitting is up to 150 pounds per square inch (psi). This fitting meets National Sanitation Foundation (NSF)/American National Standards Institute (ANSI) standards 14, 51, and 61 for plastic piping systems, food equipment materials, and use with drinking (potable) water.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Push-to-connect compression fittings do not require tools or sealants, and are useful in installations where a heat source, such as a soldering torch, is prohibited. When purchasing pipe fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).

John Guest manufactures push-to-connect fittings and pipe and plastic plumbing systems. The company, founded in 1961, is headquartered in Great Britain and meets International Organization for Standardization (ISO) standard 9001.

Beware LG blue tubing...

Beware LG blue tubing...
If you use this to patch in a piece of polyethelene tubing to your LG refrigerator blue tubing...the teeth in this will slowly cut through the blue plastic tubing..it may take a year but all of a sudden you may hear a big pop and then water all over when the ice maker tries to fill...happened twice to me..did not cut the repair piece..but cut through the blue existing tubing..I reccomend a brass fitting ...Legines Brass Compression Tube Fitting, Union, 5/16" OD x 5/16" OD, Pack of 2...from amazon..this does not have teeth that can cut the tubing and will give a permanent fix when you splice in the repair piece...
Thank you for your feedback
