Overview
TASK-LINE® Design
Through a proprietary process, FDA-approved, pure virgin PTFE resin is compression molded around and through a heavy-gauge, 304 stainless steel, perforated, metal insert. After oven sintering, the porous-free PTFE resin 100% encapsulates the stainless insert, isolating it from any fluid contact while in service.
No More Fabrication or Gaskets
TASK-LINE pipeline fluid blockers (line blockers) are molded to size, 1" through 8" (other sizes available upon request) in class 150# ANSI dimensions 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. TASK-LINE line blockers self-align and seat easily to any 150# ANSI flange and never require gaskets.
TASK-LINE® Benefits
In terms of performance and longevity, TASK-LINE pipeline fluid blockers set the standard. Lined blockers have a temperature range from cryogenic to +400°F and are chemically resistant to: all acids, all chlorides, all sulfates, all bleach solutions, all solvents, all phenols, all caustics, and all peroxides. TASK-LINE pipeline fluid blockers are leak-free and bubble-tight and can be used over and over without sacrificing sealing ability. And TASK-LINE line blockers have zero corrosion rates which contribute to lower life-cycle costs when compared to fabricated or competitive allow paddles.
To be used as temporary fluid blockers during maintenance of downstream equipment.
TASK-LINE® Advantages
- Save over 75% in procurement and installation
- Quick and easy installation
- No gaskets required
- No fabrication/waste
- Zero corrosion rate
- Blowout protection
- Reusable
- Non-porous
- Seats easily/releases easily

Limits
When installed between two flanges, TASK-LINE line blockers block out all pipeline fluid. The PTFE-encapsulated metal insert reduces any radial flow which eliminates bolt retorquing after installation, maintaining a bubble-tight seal. The strength of the metal insert also provides critical, blowout-proof protection. Another benefit of TASK-LINE Composite ball valve Superior features / Chemical services line blockers is the PTFE's non-stick property which allows it to easily release from flanges during disassembly without any scraping.
