Our Products

Products
by Application

Engineered for every sealing defense challenge from tip to tail.

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.

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.

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.

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.

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.

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.

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.

Interior Seals

Interior Panels, Sidewalls & Galley Areas

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

DEFENSE PLATFORMS

Our products protect systems across every domain. From fighters at Mach 2+ to submarines at crush depth, we offer custom-engineered seals for critical missions.

Military Aircraft

Sealing products and components for fighters, bombers, transports, and rotorcraft. From fuel systems to canopy seals, our components perform at Mach 2+ and beyond.

Ground Vehicles

Armored vehicles, tactical transports, and support equipment operating in extreme conditions — from desert heat to arctic cold.

Weapons Systems

Missiles, munitions, and targeting systems require precision sealing that performs perfectly — the first time, every time.

Naval Vessels

Surface ships and submarines demand seals that withstand saltwater, extreme pressure differentials, and decades of reliable service.

Why We’re Fast

Complete Vertical Integration

Most real manufacturers rely on external suppliers for compounds and tooling. We control the entire chain.

Step One

Proprietary
Compounds

We formulate and mix our own compounds in-house. Custom formulations engineered for your exact application — developed over decades of material science expertise.

Step Two

In-House
Design

Our engineers design your solution and manufacture tooling under one roof. Direct collaboration from design to tool-ready — FEA analysis, 3D prototyping, and material selection all happen here.

Step Three

Integrated
Manufacturing

Complete production control in Long Beach, CA. From design to finished parts — molding, extrusion, assembly, and testing all under our roof. NPI (New Product Introduction) programs managed through dedicated cell.
