China grooved o ring Manufacturers Factory Suppliers

Product Details: Grooved o-rings are designed for various sealing applications, including static, dynamic, and face seal configurations. Key product details include the o-ring cross-section size, gland depth, squeeze percentage, and groove width. For example, AS568B standards specify different dimensions for static, dynamic, and face seal glands. The gland depth and groove width are critical for ensuring the proper squeeze and preventing o-ring extrusion or failure[1][2][5].

VITON Quad Ring From China

Product Details: Viton Quad-Rings, also known as ‘x’ profile O-Rings, are four-lobed seals with a specially developed sealing profile. They are made from a wide range of elastomer materials, including Viton/FKM, and can be used in various static and dynamic sealing applications. These seals provide twice the sealing surface compared to standard O-Rings and require less squeeze to maintain an effective seal. The four-lobed design prevents the seal from rolling in the groove during reciprocating movement and reduces friction, leading to less wear and a longer service life. The parting lines are between the lobes, away from the sealing surface, eliminating leakage

issues. They are measured by their Cross Section and I.D., similar to O-Rings, and are self-energizing double-acting sealing elements[2][4].

Pros:
– Provides twice the sealing surface compared to standard O-Rings
– Requires less squeeze to maintain an effective seal, reducing friction and impro…
– Prevents the seal from rolling in the groove during reciprocating movement
– Less wear due to low friction
– Improved startup with a lubricant reservoir formed between the sealing lips
– Increased stability in dynamic applications
