PEX-A is the most expensive of all 3 types and other than slightly greater flexibility than the other (2) types, there are no significant advantages of this type over the other two. Great for all radiant applications easier to install for a person who is a novice due to greater flexibility.
PEX-B Houseneeds elects not to sell PEX-B because we prefer the properties of PEX-A and PEX-C over the PEX-B.
PEX-C is the latest addition to PEX line and price-wise is less expensive than PEX-A. Unfortunately, the cross-linking process for this type creates the least amount of bonds (vs. the PEX-A) therefore, the flexibility of the this product is less than PEX-A. If the PEX tubing becomes kinked during handling, it can be re-formed to its original shape by heating it with an electric heat gun to a temperature of approximately
275F.The tubing will pale slightly when heated and become pliable as the shape restores. Do not overheat, and allow to completely cool undisturbed. Otherwise, you may have to cut out the kinked section and fix it with a mechincal union. PEX-C can be used with a large variety of installation methods. Our PEX-C is Heat and Domestic Potable Water Approved.
