SKU CH-42WK-9M702

White joint-sealant tape 1/2 in wide by 15 ft long seals threads up to 1-1/2 in from -400 °F to 600 °F at 3,000 psi

  • Handles extreme heat up to 600 °F
  • Remains flexible in cold down to -400 °F
  • Seals threads up to 1-1/2 in diameter
  • Withstands 3,000 psi liquid and gas pressure
  • 15 ft roll covers multiple gasket jobs

1/2-Inch Wide Gasket Tape

This white joint sealant tape measures half an inch wide and fifteen feet long. It is designed for general-purpose thread sealing on pipe diameters up to one and a half inches. The material suits plumbing, HVAC and industrial maintenance jobs where a reliable gasket is needed quickly.

Temperature and Pressure Performance

The tape operates continuously from minus four hundred degrees Fahrenheit up to six hundred degrees Fahrenheit. It withstands liquid and gas pressures of three thousand psi across that range. Linear density stays between one point two and one point five grams per cubic centimetre for consistent fill.

Ready-to-Use Form Factor

Supplied as a single roll, the tape requires no mixing, curing time or additional compounds. Users simply wrap the threads and assemble the joint for an immediate seal. The format reduces waste and eliminates the need for separate paste or anaerobic adhesive inventories.

Questions about this item

How do I install the 1/2 in wide tape on threads up to 1 1/2 in diameter without gaps?

Wrap the tape clockwise on clean male threads, overlapping each turn by half the 1/2 in width so the 15 ft roll covers the full 1 1/2 in diameter without voids.

When will the white joint sealant tape need replacement in a sealed system?

Replace the tape whenever the joint is broken or during scheduled maintenance; the material remains stable from -400 °F to 600 °F and at 3,000 psi for liquids or gases.

What is the first performance limit reached during continuous high-temperature service?

The 600 °F maximum operating temperature is the first hard limit; above it the tape can lose sealing integrity even though pressure ratings stay at 3,000 psi.
