Power Generation

Precision Seals
for Energy

Energy infrastructure demands sealing solutions that perform under extreme pressure, temperature, and chemical exposure — from traditional power generation through next-generation sustainable energy systems. Where safety and reliability are essential, there is no room for error.

Our Products

Products
by Application

Engineered for every sealing challenge — from aerodynamic surfaces to extreme thermal environments.

Custom Applications

PTFE Seals, Eye Guards, Injection Molding, Diaphragms, Ablatives and Insulation, RTV

When standard catalogs run out and competitors won’t take the call, engineering teams come to Rubbercraft. We’ve spent over a century developing one-of-a-kind solutions for the environments where conventional seals fail.

Fire Seals

AC20-135 Fire Seals, fireproof, fire-resistant

Highly engineered fireproof and fire-resistant barrier seals for commercial and military engine, pylon, and nacelle environments. Approved to AC20-135 and tested because when fire protection is the requirement, there is no room for uncertainty.

Rubber to Metal Bonded Seals

Plate seals, co-molded gaskets

Precise co-molding processes that vulcanize an elastomeric seal profile directly into a non-elastomeric carrier — producing a chemical bond far superior to adhesive alternatives. Zero air traps. Zero bond line contamination.
