When sourcing Custom Rubber Gaskets for your business, choosing the right manufacturer is critical. This comprehensive guide covers everything you need to know about custom rubber gaskets, helping you make informed decisions for your procurement needs.

What Are Custom Rubber Gaskets?

Custom rubber gaskets are essential components used across industries including automotive, medical, electronics, and consumer goods. At Anlintech, we specialize in custom manufacturing of high-precision rubber and silicone parts from our ISO 9001:2015 certified facility in Dongguan, China.

With over 16+ years of experience in rubber and silicone manufacturing, we understand the critical role that material selection, precision molding, and quality control play in your supply chain success.

Key Material Options for Rubber Gaskets

Selecting the right material is the foundation of a successful custom rubber gaskets project. Here are the key materials we work with:

• NBR (Nitrile): Excellent oil and fuel resistance, -40°C to +120°C operating range. Ideal for automotive and industrial applications.
• EPDM: Superior weather and ozone resistance, -50°C to +150°C. Perfect for outdoor and weather-exposed applications.
• Silicone: Wide temperature range -60°C to +230°C, excellent electrical insulation, FDA-compliant grades available.
• FKM (Viton®): Outstanding chemical and high-temperature resistance, -20°C to +250°C. For demanding chemical and automotive applications.
• Neoprene: Balanced properties with good weather and moderate oil resistance. Commonly used in gaskets and seals.
