Strong. Reliable. Long lasting.
Say goodbye to spiral wound seals. Compared to Black-Max spiral wound gaskets, it seals better and has much better regenerative properties. They also weigh less than half the weight of spiral seals, making them easier to handle and save on shipping fees. And while spiral seals require near-perfect conditions, Black-Max seals seal on rough, pitted surfaces with less pressure load.

No leakage under pressure.
Even the slightest leak will increase maintenance requirements and reduce your lifetime of the product.
Field tests by major end users confirm this The BLACK-MAX seal seals with zero vapor leakage and during hydrotests in cold water.
BLACK-MAX® resists working steam temperatures up to 1200°F. Rubber gaskets cannot withstand such pressure and heat.
Easy removal. Removal is easy and requires no scraping, chopping or grinding – resulting in lower maintenance costs and less downtime.
Clearly marked sizes. The size of each seal is permanent marked so you’ll immediately know you have
one you need.
Maximum sealing on rough surfaces. Gross and
pitted surfaces on old or poorly maintained flanges represent
no problem for BLACK-MAX seals: material
it is flexible enough to adapt perfectly to the surface
topography and maintain the tightest seal.
Chemical resistance. Own graphite used to be
BLACK-MAX production is chemically inert (pH 0 -14)
and resistant to chemicals used in boiler water treatment.
Custom BLACK-MAX seals are no problem and can
be designed and manufactured with no tooling fees!
