In 2011 Congress enacted the Reduction of Lead in Drinking Water Act to amend the Safe Drinking Water Act's section regarding the use and introduction into commerce of lead pipes, plumbing fittings or fixtures, solder and flux. The Act established a prospective effective date of January 4, 2014, which provided a three year timeframe for affected parties to transition to the new requirements. All of the metal fixtures and fittings sold by H2O Distributors are compliant with this act.
H2O Distributors is proud to feature American-made products on its web site.

Fitting grips before it seals. Ensure tube is pushed into the tube stop.
Push the tube into the fitting, to the tube stop. The collet (gripper) has stainless steel teeth which hold the tube firmly in position while the O-ring provides a permanent leak-proof seal.
Pull on the tube to check that it is secure. It is a good practice to test the system prior to leaving site and/or before use.
To disconnect, ensure the system is depressurized before removing the tube. Push in collet squarely against face of fitting. With the collet held in this position, the tube can be removed. The fitting can then be re-used.
