Types and uses of silicone seals

Silicone seals are divided into: U-shaped seals and Y-shaped seals.

Let's take a look first: U-shaped sealing ring, U-shaped sealing ring is a kind of soft silicone material, mainly using 100% food grade silicone as raw material, high transparency, strong tear resistance, aging resistance and no stickiness! It can absorb any level of glass, ceramic or stainless steel cup mouth, good sealing performance, slow down the aroma of juice, tea or coffee in the cup, can also use the air pressure to lift the whole cup, and in daily use Can also be protected against dust!

There are many types of Y-rings, and the materials include natural rubber (NR), silicone rubber (SI) styrene rubber (SBR), butyl rubber (LLR), hydrogenated nitrile (HNBR), ethylene propylene rubber (EPDM), butyl Nitrile rubber (NBR), neoprene (CR), fluorosilicone rubber (FLS), fluorine rubber (FPM), perfluoroelastomer (FFPM), acrylic rubber (ACM), polyurethane rubber (PU). The above materials have different uses and purposes, including oil resistance, chemical resistance, high and low temperature resistance, and wear resistance. Therefore, when selecting the Y-shaped seal ring specifications, it is necessary to understand the use of the product, the pressure, function and service life to be able to effectively select the required Y-shaped seal ring material.

Let's take a look at the specifications of silicone seals，

U-shaped silicone seal ring specifications: 10 * 25 * 9 ，32 * 52 * 10 ，110 * 140 * 16， 12 * 40 * 10， 35 * 55 * 10， 135 * 165 * 20, etc. The first number is the inner diameter, the middle one is The outer diameter, the last one is the height of the product.

Specification of Y-shaped silicone seal ring: 10 * 18 * 4， 45 * 65 * 10 ，110 * 140 * 15 ，360 * 400 * 30 etc. Inner diameter × outer diameter × height.

The above seal ring specifications provide reference; the size can be customized according to product requirements. The outer diameter, inner diameter, height and tolerance range of the seal ring are marked on the engineering drawings. There will be tolerances for each product size. MM, the outer diameter tolerance size standard is +/- 0.07MM.
