Red Thread IIA Riser Pipe

The industry’s first corrosion-resistant fiberglass riser pipe.

Description

Our Red Thread™ IIA riser pipe assembly was purpose-built to be durable, long-lasting, and compatible with tools that fit through a 4-in. Schedule 40 steel pipe.

Features

  • Minimum wall thickness of 0.145 in.; more than twice the thickness of standard Red Thread IIA pipe
  • Inside diameter (ID) of 4.026 in.; identical to 4-in. Schedule 40 steel pipe
  • Total assembled length of approximately 68 in. when using standard 5-ft length of riser pipe

Benefits

  • Corrosion-resistant FRP materials means no more stuck tools that do not fit through your riser
  • Compatible with ultra-low-sulfur diesel (ULSD) and all current fuels
  • The ID of the assembly is designed to accommodate most standard tools, such as drop tubes, fill tubes, and overfill prevention valves.
  • Assembled length designed to be ideal for a maximum tank burial of 7 ft below grade
  • Durable Red Thread IIA riser pipe uses significantly greater wall thickness to better withstand surface loading.
  • Red Thread riser adapters have thicker walls and are lengthened to accommodate the thicker walled Red Thread IIA riser pipe.
  • Both the pipe and adapters are made with the exact same materials used in our standard Red Thread IIA pipe.
  • Ideal for use on both steel and fiberglass tanks 
  • Approved for both direct-bury and use inside a sump
  • Pipe sized for application, making shipping easier and more cost effective
  • Pipe can be cut and tapered in the field using existing tools
  • Uses PSX-20 adhesive  
  • No pipe threading required as with metallic risers

  • Red Thread™ IIA Riser Pipe is UL-971 listed in both the US and Canada
  • RP100 allows for the use of non-metallic Riser Pipe. See section 10.13 of the latest RP100 document from PEI for more information.
