by Application
Engineered for every sealing challenge — from aerodynamic surfaces to extreme thermal environments.
Why We’re Fast
Complete Vertical Integration
Most seal manufacturers rely on external suppliers for compounds and tooling. We control the entire chain.
1
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.
2
Step Two
In-House
Design
Our engineers design your solution and 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 cells.
We’re with you every step of the way
Complete vertical integration with full engineering support. Unmatched speed, quality, and control from one source.

Case Study
Radome Seal: Design-to-Delivery to Meet Program Needs
When a defense contractor needed a complex seal solution with an impossible timeline, Rubbercraft’s vertically integrated approach delivered production-ready parts — on time, first article approved.
Case Study
3D Printed RTV Tooling
A space program needed cision RTV silicone covers but faced end-of-life tooling, non-conforming parts, and volumes that didn’t justify hard tooling. RCC proposed a hybrid approach — 3D printed patterns with RTV molds — cutting tooling lead time from weeks to days with zero hard tooling investment.
