All-Flex Risers

Our fully approved Servi-Sert All-Flex riser kits (1/2" or 3/4" IPS male pipe thread with 1/2" CTS .090 wall capabilities) are available in 84" lengths for the first-stage regulator tank side and 36" lengths for the second-stage regulator house side.

Sold in kit form, as required by NFPA-58/ 1998 Edition, these risers feature pull-out proof, third-party design certified Servi-Sert service heads, and PVC sunlight resistant coated steel flex that meets crush strength requirements. They are lined with a plastic centering device that provides an annular insulating air space, and a moisture seal permanently affixed to the end of the riser provides moisture, corrosion and shear control.
