Boiler Gaskets

Hi-Tech Gasket supplies boiler gaskets in Blue-Max® style, TOPOG-E®, and any of our in-house sheet materials. Boiler gaskets are manufactured in oval, obround, rectangular, round, and square shapes.


Blue-Max® gaskets were developed as a substitute for asbestos gaskets. They are composed of a tacky cloth of glass, synthetic fibres, and brass wire, impregnated with a blue elastomer compound. The final formed product is coated in a PTFE material.


The Black-Max® gasket is composed of graphite with multiple layers of stainless steel 316 foil inserts. The gasket is fit for service in -240°C to 454°C in oxidizing atmospheres and 650°C in steam service.

Screw Packing

Four primary styles:
  • homogeneous hydrogenated nitrile
  • individual graphoil rings
  • stacked graphoil rings with tops and bottoms preformed from graphoil rope packing

  • bonded stack of graphoil rings with tops and bottoms made of stainless steel 316

Pipe Roller

BoKure™ urethane possesses exceptional load bearing abilities and wear resistance. These characteristics make it the ideal material for custom pipe rollers. Contact us for more information.

Fibreglass Tape

Fibre glass rope offers strong characteristics such as resistance to heat and abrasion, while insulating from electricity. Fibre glass rope is available in diameters 1/4” to 2”.

Applications: pipe wrap, boiler, furnace, oven, gas fireplace, wood/gas/tile stoves, thermal insulation, glass manufacturing, flange gasketing and fireproof safe applications.


PTFE tape is an ultra-thin material typically used to seal pipe threads.
The material provides you with near universal chemical resistance.

Mud Plug Kits
