Dual-Durometer Seals: 10,000 psi Service
A custom dual-durometer seal which features a 70 Shore D base material chemically bonded to a standard lip material. This unique construction allows for increased extrusion resistance at the base with excellent sealing capabilities at the lip and service loads up to 10,000 psi. Depending on your particular application, alternate materials are available with custom colors and branding of your parts.
Application Support
Whether you require technical support, drawings or just some general information about seals and sealing materials, we will be able to help you with your questions. We offer flexible, fast and convenient solutions for sealing applications.
An unlimited range of special and custom profiles manufactured exactly according to specifications in a wide range of standard and custom materials. We provide drawings, technical expertise and we manufacture samples and working prototypes within five days or less.
Bumpers, Wheels and Special Products
Custom manufacturing capabilities for molding polyurethane into a wide variety of specialized products including bumpers, wheels, flanges, bushings and scrapers. Ask us about our range of options supported by in-house tooling, custom part numbering and material alternatives as required.
In-House Tooling
Our computer-aided design system means faster manufacturing, production and turnaround times. In-house tooling decreases pre-production lead times and helps manage overall tooling costs. It also facilitates making adjustments on-the-fly to ensure that tolerances are met and quality is guaranteed. Our expertise and experience allows Nuraseal to spend more time making your products, and less time waiting for tooling.
