Colvin Friedman manufactures precision neoprene gaskets engineered for applications requiring balanced oil resistance, weather durability, and reliable sealing performance. With over 75 years of die-cutting experience, we transform polychloroprene rubber into custom gaskets that meet tight tolerances across automotive, marine, industrial, and construction sectors.
Neoprene gasket manufacturing demands expertise in material behavior, die design, and quality control. Our California-based facility produces custom gaskets from prototype through full production runs, delivering the precision and consistency your application requires.
What Makes Neoprene Ideal for Gasket Applications
Neoprene (polychloroprene rubber, CR) offers a balanced combination of properties that make it suitable for diverse sealing applications:
We offer two primary manufacturing methods optimized for different production requirements:
| Manufacturing Method | Best For | Specifications |
|---|---|---|
| Flatbed Die Cutting | Low to mid-volume runs, thicker neoprene (up to 0.5"), larger gaskets | 2,000–4,000 parts/hour capacity, ±0.010" tolerance, max width 40" |
| Rotary Die Cutting | High-volume runs, thinner neoprene (up to 0.015"), precision requirements | 40,000 parts/hour capacity, ±0.005" tolerance, max width 16" |
We stock and convert neoprene in multiple durometers and thicknesses:

01
We begin with a technical consultation to understand your application requirements. Our team evaluates factors including:
If you’re uncertain whether neoprene is the optimal material, we can recommend alternatives based on your specific environment.
02
Our engineers create precision dies using CAD/CAM systems. For rotary applications, we manufacture custom cylindrical dies. For flatbed work, we use steel rule, forged, or etched dies depending on complexity and production volume.
03
Before full production, we manufacture prototype gaskets for testing fit, form, and function. This stage enables design refinement, ensuring the gasket meets its performance requirements.
02
We execute production runs on our servo-driven or line-driven presses, maintaining consistent quality through automated sheet feeding and part collection. Our QMS (Quality Management System) monitors critical dimensions throughout production.
03
Every production run undergoes dimensional inspection and visual quality checks. We package gaskets to your specifications and can ship directly to your facility or distribution centers.
| Application | Description |
|---|---|
| Automotive Applications | Neoprene gaskets are used in automotive applications that require moderate oil exposure and temperature cycling. Common uses include engine compartment seals, fuel system components, and weatherstripping where flame resistance is beneficial. |
| Marine and Outdoor Equipment | Saltwater resistance and UV durability make neoprene ideal for boat hull gaskets, engine compartment seals, deck hardware, and marine equipment that require long-term weather protection. |
| Industrial Manufacturing | Used in pump housings, valve seals, equipment enclosures, and machinery components exposed to oils, moderate chemicals, and temperature fluctuations. |
| Construction Equipment | Neoprene’s abrasion resistance and weather durability support construction machinery gaskets working in dusty, outdoor, and high-impact environments. |
| Electrical and HVAC Systems | Flame-resistant neoprene gaskets protect electrical enclosures and HVAC equipment, ensuring sealing performance and fire safety compliance. |
With over 75 years of die-cutting expertise, Colvin Friedman has been a trusted partner to OEMs and high-volume manufacturers since 1949. From thousands of custom designs across diverse industries and materials, our U.S.-based production facility in California ensures precision, reliability, and an average lead time of three weeks, eliminating overseas delays and providing consistent turnaround. Customers work directly with our Vice President, Josh Rodman, ensuring clear communication and technical oversight on every project.
Our commitment to quality is reflected in a 99.99% on-time delivery rate, zero recorded quality rejections, and a 100% project completion record. Whether you need short prototype runs or full-scale production, every gasket is custom-manufactured to your specifications.
Based in Petaluma, California, Colvin Friedman has provided precision die-cutting services since 1949. We specialize in flatbed and rotary die cutting, narrow and wide web converting, and lamination services for OEMs and high-volume manufacturers across the United States. Our direct, personal approach combines the capabilities of a large production facility with the responsiveness of a small business.
Whether you need prototype gaskets for product development or scaled production for ongoing manufacturing, Colvin Friedman delivers precision neoprene gaskets with predictable lead times and zero-defect quality.
Get Started:
We typically respond to quote requests within 24 hours, providing a preliminary feasibility assessment and lead time estimates.
Neoprene gaskets operate effectively from -40°F to 250°F (-40°C to 121°C), with optimal performance between -20°F and 200°F. For applications requiring continuous exposure above 200°F, we recommend high-temperature alternatives, such as Viton.
Yes. Neoprene provides good resistance to petroleum-based oils, greases, and many hydraulic fluids. While nitrile rubber offers superior oil resistance for severe petroleum exposure, neoprene’s balanced properties make it ideal when moderate oil resistance must be combined with weather durability and flame resistance.
EPDM offers superior long-term weather resistance but lacks resistance to oil. Silicone handles higher temperatures but has poor tear strength. Neoprene provides the optimal balance when you require moderate oil resistance, good weather protection, and flame resistance in a single material.
Yes. We can source FDA-approved neoprene formulations for food-grade and potable water applications. Compliance requirements should be specified during the design consultation phase.
Yes. We laminate pressure-sensitive adhesive (PSA) backing to neoprene and provide kiss-cutting to create peel-and-stick gaskets. Multiple adhesive strengths and types are available based on your bonding surface.
Neoprene is not recommended for concentrated mineral acids, strong caustic solutions, aromatic hydrocarbons (benzene, toluene), ketones, or ester solvents. For these environments, we can recommend fluoroelastomers or specialized compound
