O Ring

Product Details:

Gapi O-rings are industrial-grade sealing solutions manufactured by the Gapi Group, available in a variety of materials and sizes for diverse applications. They are designed for reliable sealing performance in both static and dynamic applications, including hydraulic systems and automotive uses. Materials and SpecificationsGapi O-rings are manufactured in a wide range of standard and custom materials including NBR, Viton/FKM, EPDM, Silicon, and Polyurethane (PUR), to suit various applications and environments. These materials offer different properties such as resistance to oil, fuel, heat, chemicals, and environmental factors, with specific temperature ranges and hardness levels detailed in referenced documents. Gapi produces O-rings in over 4000 standard sizes in both imperial and metric dimensions, with inner diameters varying from less than 1mm to over 800 mm. 

Product Details:

Viton O-rings, also referred to by the ASTM designation FKM, are highly durable seals known for their exceptional resistance to high temperatures, chemicals, oils, and fuels. They are widely used in demanding applications such as the aerospace, automotive, and chemical processing industries due to their reliable performance in harsh environments. 

Product Details:

NBR O-rings are available in a wide array of sizes, typically conforming to both metric and imperial (SAE) standards, which can be purchased individually or in comprehensive assortment kits.


NBR (Nitrile Butadiene Rubber) O-rings are manufactured in a vast range of dimensions to suit nearly any application, from less than 1 mm inner diameter to over 800 mm. Sizes are generally based on standardized measurements, ensuring compatibility across various industries. 

• Metric Sizes: Common metric cross-sections (thicknesses) include 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, etc., with inner diameters available from tiny sizes up to very large dimensions (over 1000 mm).
• Imperial (SAE) Sizes: Standard imperial sizes, often referenced by "dash" numbers (e.g., -004, -005), have common cross-sections such as 1/16", 3/32", 1/8", 5/32", 3/16", 1/4" and inner diameters ranging widely from small to large.
• Hardness: The standard hardness for NBR O-rings is 70 Shore A. Other hardness options, such as 40, 50, 80, and 90 Shore A, are also available for specific pressure and application requirements. 

Product Details:

An X-ring seal, also known as a quad-ring seal, is a four-lipped mechanical seal with a distinctive X-shaped cross-section, providing superior sealing performance and durability, especially in dynamic applications. It is used as an alternative to the traditional O-ring seal to overcome issues like spiral twisting and high friction.
