- Constructed of the highest quality steel, the HTX and SXHT are true work horses. HTX comes standard with a 100% butyl diaphragm. SXHT goes even one step further with our patented CAD2 diaphragm, offering even lower permeability rates at higher temperatures. Additionally, both tank lines' diaphragms are oversized, which maximizes drawdown and minimizes wear. This design feature virtually eliminates diaphragm stretch, further promoting longevity.
