Amtrol WX202 WX-202 WELL-X-TROL Expansion Tanks

Product Features:

• High-strength steel shell
• Virgin polypropylene inner liner will not crack, chip, flake or peel
• Thick butyl rubber diaphragm offers the lowest permeability of any material used today and will not support bacterial growth
• Heavy duty butyl diaphragm is the thickest in the industry and features seamless construction for uniform strength and flexibility. It conforms exactly to the shell configuration without stretching, creasing, or forming bubbles or corners that could trap water or sediment. Butyl is the best known elastomer to prevent air loss.
• Diaphragm design will not collapse or tear like bladder designs
• Stainless-steel system connection withstands aggressive water
• Welded air valve is permanently attached rather than mechanically threaded to prevent loss of air pressure and to minimize stress on the well's pump system. It also carries a tamper-evident warning label.
• Deep-drawn steel domes offer twice the strength of rolled steel while minimizing weight.
• Unique positive hoop ring seal secures diaphragm and liner for added strength and reliability.
• Polypropylene liner provides a 100% corrosion resistant, non-metallic rigid water reservoir that is listed by NSF® International Standard 61.
