To combat the effects of pressure and temperature fluctuations, flexibility and recovery are essential. Masterpac Spiral Wound Gasket with Micatherm filler is the precision-engineered solution for flanged joints, heat exchangers, boiler handholes, manholes, and other high-temperature, high-pressure applications - providing resistance to virtually every known corrosive and toxic element. Masterpac Spiral Wound Gasket uses Micatherm filler material which has max temperature to 1000ºC and Class 150 to 2500.

Masterpac SWG style  ORWIR  is recommended for high pressure/temperature applications. Both rings act as a compression limiter and provide protection from the process media at the same time.

Typically used with flat face and raised face flanges and specified for high pressure and temperature service or where corrosive or toxic media are present.

Masterpac SWG style ORW has an integral centering in order to assures fast and accurate centering of the gasket on the flange. It also acts as a compression limiter to prevent over compression of the winding.

Typically suitable for using with flat face and raised face flanges.

The major advantages of our SWG style WIR are protecting windings against media and pressure, reduce turbulent flow of process media, and minimize erosion of flange faces. Thank you to the Inner metal ring that acts as a compression stop and fills the annular space between flange bore and the inside diameter.

Typically used for male-to-female pipe flanges.

Masterpac SWG style winding-only (W)  is the simplest style which consists of inner and outer diameters that reinforced with several “V” shaped metal strip. The major benefit of this design includes providing greater stability and better compression characteristics. Our SWG style W can be manufactured in different patterns including round, obround, oval, rectangle, diamond, pear and so on.

Typically used in tongue &  groove, male-to-female, groove-to-flat, and OEM applications.
