PureFlex® TASK-LINE® Pipeline Fluid Line Blockers

In terms of performance and longevity, PureFlex® TASK-LINE® pipeline fluid blockers set the standard. Line blockers have a temperature range from cryogenic to +400°F and are chemically resistant to all acids, chlorides, sulfates, bleach solutions, solvents, phenols, caustics, and peroxides. TASK-LINE pipeline fluid blockers are leak-free, bubble-tight, and can be used over and over without sacrificing sealing ability.

Product Features & Benefits

  • HANDLES AN EXTREME TEMPERATURE RANGE: TASK-LINE® lined pipe fluid line blockers have a temperature range of cryogenic to 400°F.
  • NO MORE FABRICATION, EASY INSTALLATION: they are molded to size, 1” through 6” (other sizes available upon request) in class 150# ANSI ratings with a nominal thickness of 1/8”. Installation and removal are a snap with its integral molded paddle handle. The handle extends 2” above the flange and has a pre-drilled 3/8” hole for tagging (while in service) or hanging (while in storage). The handle can be factory painted for identification purposes. 
  • CHEMICAL RESISTANT: to all acids, chlorides, sulfates, bleach solutions, solvents, phenols, caustics, and peroxides.
  • LEAK FREE AND REUSABLE: TASK-LINE® The handle can be factory painted for identification purposes. TASK-LINE line blockers self-align and seat easily to any 150# ANSI flange and never require gaskets.
  • ZERO CORROSION: TASK-LINE line blockers have zero corrosion rates which contribute to lower life-cycle costs when compared to fabricated or competitive alloy paddles.
  • NON-CONTAMINATING: Independent laboratory testing has proven that TASK-LINE® grounding paddles are non-contaminating and non-leaching. This limits the possibility of process contamination.
  • BLOWOUT PROTECTION: the strength of the metal inserts provides critical blowout-proof protection.
  • SEATS EASILY/RELEASES EASILY: TASK-LINE® line blockers self-align and and the PTFE non-stick property allows it to easily seat and release easily to any 150# ANSI flange and never require gaskets.
