Custom High Precision Fpm Ffkm Hnbr Nbr Fkm Silicone Epdm Rubber Oring Seals O-ring O Rings

SBT offers high-precision custom rubber o ring seals engineered for reliable performance in demanding industrial environments. These industrial o ring seals provide effective sealing for static, dynamic, and rotary o ring sealing applications, preventing leakage of oil, water, gas, or chemical media while maintaining long service life. Available in a full range of materials including FKM o ring, Viton o ring, NBR o ring, FFKM, HNBR, Silicone, and EPDM, our custom o ring sizes and designs deliver superior extrusion resistance and interchangeability across standardized grooves.

A custom rubber o ring seal is a toroidal-shaped elastomeric component designed to fit into a groove and create a tight seal between two or more parts. It is one of the most versatile and widely used sealing solutions in modern industry, offering simple yet highly effective performance for both static dynamic o ring and rotary o ring sealing needs.

• Any environment requiring reliable custom rubber o ring seals for leak prevention

How O-Rings Work

How o rings work is based on the principle of elastic deformation: when compressed in a groove, the custom rubber o ring seals against the mating surfaces, creating a positive barrier that blocks fluid or gas passage. Under pressure, the o-ring is further energized to enhance sealing force. In rotary o ring sealing applications, the design accommodates relative motion while maintaining contact and lubrication to minimize wear. This results in zero leakage, low friction, and reliable performance across a wide range of pressures and temperatures.

Complete O-Ring Installation Guide

O ring installation is simple yet critical for optimal performance:

1. Preparation: Clean the groove and mating surfaces thoroughly; inspect for burrs or damage.

2. Lubrication: Lightly coat the custom rubber o ring seals with compatible lubricant to ease assembly.

3. Positioning: Place the o-ring into the groove without twisting or stretching excessively.

4. Assembly: Carefully mate the components and ensure even compression.

5. Testing: Pressure test the assembly to verify no leakage.Pro Tips: Use proper tools to avoid nicks; follow recommended squeeze (typically 15-30%) and groove dimensions. Correct o ring installation prevents premature failure and ensures long-term sealing integrity.
