Our Products

Products for Commercial Aviation

Engineered for commercial aviation’s most demanding sealing environments.

Aerodynamic & Airframe Seals

Wing, slat, spoiler, door, window & panel seals

Aerodynamic and airframe seals optimize aircraft performance by controlling airflow, maintaining cabin pressure, and protecting critical systems from moisture, contaminants, and extreme operating conditions.

Interior Seals

Interior Panels, Sidewalls & Galley Areas

Sealing systems for every interior environment — cabin panels, floors, lavatories, ECS ducting, windows, and cargo compartments.

Cockpit & Window Seals

Cockpit & Cabin Window Wiper Blade Seals

Advanced glazing seal systems for aerospace applications — providing environmental isolation, pressure retention, structural support, and vibration management between aircraft glazing and surrounding fuselage structure.

Composite Fabrication Tooling

Elastomeric Tool Fabrication

A proven track record of supplying elastomeric tooling solutions for composite fabrication — supporting co-curing, co-bonding, and fabrication of single-piece complex structures. Eliminating secondary bonding, lowering costs, and improving laminate quality.

Conductive Seals and EMI Shielding

Avionics, Communication Systems, EMI RFI Suppression

Conductive elastomeric seals and EMI shielding components — engineered to provide electrical continuity, environmental sealing, and vibration isolation in a single integrated component.

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.

Inflatable Seals

Canopies, doors, hatches

Dynamic sealing performance and reliability. Inflatable seals create air- or watertight barriers by inflating and maintaining consistent air pressure, making them the ideal solution for uneven surfaces, misaligned gaps, and applications that demand instant access.

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.
