Permabond® HH190 Gasketmaker is an anaerobic curing flange sealant that can replace, or be used as a dressing for, conventional pre-cut gaskets. Since HH190 is a flowable paste, it conforms to the shape of the flange. The consistency allows metal-to-metal contact of the flanges while filling the areas where no contact exists because of irregularities. HH190 results in uniform stress distribution and eliminates the need for retorquing because of stress relaxation of the flange bolts. It provides instant seal depending on the gap and flange width and ultimately seals up to 5000psi. It has excellent shock and vibration resistance and is able to be conveniently dismantled if necessary.
FEATURES:
- Eliminates pre-cut gaskets from flange assemblies
- Instant pressure seal
- Forms a tough, durable seal able to withstand high pressure
- No need to re-tighten flange bolts
- Non-flammable
- No shimming effects – better load transmission
