PSWT Pipe Sealant (With Teflon)

Description

PSWT Pipe Sealant (With Teflon) is a high viscosity and medium strength anaerobic pipe sealant. Thixotropic formulation reduces run-off and migration of the product before assembly.

  • Clean male and female threads before assembly with an absorbent tissue paper to remove any cutting oil.
  • Apply the adhesive with a 360 turn to leading threads of the male and female fittings.
  • Use an absorbent tissue paper to wipe off excess jointing compound in the direction of the thread.
  • Assembly parts and hold on for 24 hours at 22-24°C to ensure full curing of jointing compound.
  • For disassembly, use hand tools to remove mating parts. When it is hard to dissemble at room temperature, apply local heat until reaching 250°C and disassemble while hot. Then, remove any residual cured adhesive mechanically and clean parts with a proper solvent, acetone.
  • It can be easily applied to threaded joints and removed easily with hand tools.
  • With its specialized formulation, PS257 can be used applications where high pressure proof or oil resistance is required.
  • The product resists very high temperatures after full curing.
  • Especially suitable for H-thick metal threaded joints according to EN 751-1 standard.
  • The product fills high distance gaps and gives perfect results on wide-diameter (wider than 0.5mm) applications.
