1 1/2" TRUE Oxygen Barrier 500' Blue PEX tubing for heating and plumbing

This listing is for one roll of 500' of 1 1/2" Oxygen Barrier PEX B Tubing. BHS PEX tubing is made to the following specifications. OD 1.625 ID 1.244 Wall Thickness .19 Weight per foot .35 ASTM 876/877 Not to be installed in Direct Sunlight Made to ASTM specifications. Rated at 100 psi at 180 degrees. Rated at 80 psi at 200 degrees. Rated at 160 psi at 73 degrees. Type B PEX is made using the silane method (water bath).   There is a coating on the outside of the pex, so when used with pressurized boiler systems, it keeps oxygen from permeating the system and causing rust.  It is not needed with open systems or potable water systems.                   BHS PEX tubing is connected in 2 different ways. Crimp fittings are the most effective way of connecting. This is done with a barbed fitting and a copper crimp ring. The ring is compressed with the use of a crimp ring tool.  This method is the cheapest and best way to a connection and is the least susceptible to leaks down the road. You
