Cockpit & Cabin Window Seals

Sealing the
Window Interface

Every aircraft window — cockpit windshield, cabin observation, rotorcraft glazing — depends on an elastomer system holding the glass to the structure. The seal manages cabin pressure, accommodates thermal expansion, protects glazing edges, and survives decades of UV, vibration, and fluid exposure.

Pressure Retention

Cabin pressure integrity at altitude

Dual-Durometer

Soft seal + rigid retention in one profile

Custom Formulation

In-house compound development

AS9100 + Design

Approved for design

Environmental Integrity Starts with the Seal

Seals Engineered for Engineered for Pressure, Temperature, and Time

Advanced window & cockpit seals for aerospace applications — providing pressure retention, structural support, environmental isolation, and vibration management between the aircraft fuselage structure and the window assembly. From cockpit windshields to cabin observation windows to wiper blade assemblies.

Cabin pressure retention around glazing interfaces

Water, dust, salt spray, and chemical intrusion prevention

Vibration isolation and structural stress reduction

Thermal expansion accommodation between glazing and frame

Optical edge protection from chipping, abrasion, and damage

Products for
Cockpit & Cabin Window Seals

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

Proven in the Most Demanding Environments

Why Rubbercraft for Window Seals

Window sealing systems must survive thousands of pressure cycles, continuous UV exposure, thermal shock, de-icing chemicals, and decades of service — without losing compression or seal integrity.

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.
