Strong. Reliable. Long-Lasting.

Looking for a gasket that stands up to extreme pressure? That offers leak-free performance even on rough, pitted surfaces? You need the new BLACK-MAX® gasket-made from foil-reinforced, exfoliated graphite. These gaskets are made from multiple layers of exfoliated graphite foil and 316 stainless steel foil insuring gasket stability. You can use them in virtually any situation, in environments that run from a cryogenic -400°F to 1,200°F steam temperature up to 2,000 psi. Now you can standardize your gasket selection, they are available in popular shapes: Oval, obround, rectangular, round, and square

Key BLACK-MAX® Advantages

No Leakage Under Pressure.
Even the slightest leakage will increase maintenance requirements and reduce your product’s life. Field tests by major end-users confirm that BLACK-MAX® gaskets seal with zero leakage in steam and in cold-water hydro tests. BLACK-MAX® withstands working steam temperatures up to 1,200°F. Rubber gaskets can’t withstand that kind of pressure and heat.

Easy Removal.
Removal is easy and requires no scraping, chiseling or grinding – resulting in lower maintenance costs and less downtime.

Clearly Marked Sizes.
Each gasket’s size is permanently marked, so you’ll know immediately that you have the one you need.

Maximum Sealing on Rough Surfaces.
Rough and pitted surfaces on old or poorly maintained flanges pose no problem for BLACK-MAX® gaskets: the material is resilient enough to conform perfectly to the surface topography and maintain the tightest seal.

Chemical Resistance.
The proprietary graphite used to manufacture BLACK-MAX® is chemically inert (pH 0 -14) and resistant to chemicals used in treating boiler water. Custom BLACK-MAX® gaskets are no problem and can be designed and produced without tooling charges!

Say Goodbye to Spiral-Wound Gaskets

Compared to spiral wound gaskets, the BLACK-MAX® gaskets seal better and have much better recovery properties. They also weigh less than half of that of spiral gaskets, so they’re easier to handle and you’ll save on freight charges. and while spiral gaskets require near perfect conditions, BLACK-MAX® gaskets seal on rough, pitted surfaces under less compressive load.
