Product Description

Rubber Seal Ring Silicone Foam Seal Custom Flame Retardancy Auto Parts O Ring Seal Silicone Gaskets 

High-Performance Silicone Gaskets 
With their ability to withstand temperatures as high as 450°F and as low as -75°F, gaskets made from silicone rubber are highly versatile. You can find these gaskets used in a number of applications, including food processing, medical equipment, automobile engines, aerospace, pharmaceutical, energy, mobile technologies, and more. Silicone gaskets also offer excellent electrical insulation, durability, resistance to high pressures, and are flame retardant. Available in a range of colour options, these gaskets are also commonly chosen for their aesthetic value.

Common Causes of O-Ring Failure and Prevention Methods

O-ring failure is often caused by a combination of factors including improper installation, allowing for too much or too little compression in the gland design, inadequate lubrication, abrasion, or using an O-ring seal that is the incorrect size or type of elastomer for your application. Here are a few common sources of rubber oring failure and what you can do to prevent issues.



Compare & Contrast: Silicone vs. EPDM

Silicone and EPDM are similar in many ways, and the two materials offer a variety of similar characteristics. Both offer good resistance to weathering, UV exposure, and ageing, making them suitable for outdoor applications. Silicone and EPDM also exhibit high ozone resistance and an ability to remain flexible in low temperatures.

However, silicone provides far greater high-temperature resistance. Unlike EPDM, silicone will maintain its stability and physical properties in temperatures as high as 450°F (232°C).

Proper Lubrication Helps Prevent O-Ring Failure

Rubber O-rings, when not properly lubricated, can fail due to abrasion or pinching. Using an oil- or grease-based lubricant helps protect the surface of the O-ring and can prevent the degradation of the elastomer material. This will prevent failure and help extend the life of your O-ring.
