Round Metal Detectable FDA Buna-N O-Rings

Round Metal Detectable FDA Buna-N O-Rings
Metal fillers allow these food-grade round O-rings to be picked up by metal detection systems if they fall into a process stream. Buna-N is suitable for a broad range of fluids including oils, water, and mild chemicals.

Round Polyurethane O-Rings

Round Polyurethane O-Rings
Polyurethane round O-rings wear well and resist abrasion in applications requiring rubber or plastic components. Known for strong sealing ability, these O-rings are used in line shaft conveyors, robotics, engravers, and tire manufacturing.

Square Viton O-Rings

Square Viton O-Rings
Square cross section O-rings have a large continuous sealing surface for a tighter seal in static applications. Viton has good resistance to a wide range of chemicals and high temperatures.

Round FFKM O-Rings

Round FFKM O-Rings
Perfluoroelastomer (FFKM) round O-rings resist harsh chemicals and extreme temperatures. They are used as sealers in aggressive chemical environments. Typical applications include chemical, aerospace, oil and high-vacuum technology industries.

Round Soft FDA & 3A Silicone O-Rings

Round Soft FDA & 3A Silicone O-Rings
Soft formulation makes these round O-rings more compressible so that they conform better to surfaces and create a tighter seal. These food grade O-rings are 3A certified for use in food, beverage, and pharmaceutical applications. Silicone is resistant to high temperatures.

Round Soft FDA Viton O-Rings

Round Soft FDA Viton O-Rings
Soft formulation makes these round O-rings more compressible so that they conform better to surfaces and create a tighter seal. These food grade O-rings are commonly used in food, beverage, and pharmaceutical applications. Viton has good resistance to a wide range of chemicals and high temperatures.

Round Metal Detectable FDA Viton O-Rings

Round Metal Detectable FDA Viton O-Rings
Metal fillers allow these food-grade round O-rings to be picked up by metal detection systems. Viton has good resistance to a wide range of chemicals and high temperatures.

Square Buna N O-Rings

Square Buna N O-Rings
Square cross section O-rings have a large continuous sealing surface for a tighter seal in static applications. They cover more surface than round-profile O-rings and are commonly used in hose, pipe, and faucet connections.

Round HNBR O-Rings

Round HNBR O-Rings
HNBR round O-rings, or highly saturated nitrile, resist oils, mild chemicals, and water. They are more heat and abrasion resistant than Buna-N.

Round Aflas O-Rings

Round Aflas O-Rings

Aflas o-rings are resistant to high temperatures and petrochemicals.

Round Soft Buna-N O-Rings

Round Soft Buna-N O-Rings
Soft formulation makes these round O-rings more compressible so that they conform better to surfaces and create a tighter seal. Buna-N is suitable for a broad range of fluids including oils, water, and mild chemicals.

Round Fluorosilicone O-Rings

Round Fluorosilicone O-Rings
Fluorosilicone round O-rings excel in low-temperature environments and resist jet fuels and mineral oils. They are used in aerospace, automotive, and semiconductor applications. Fluorosilicone O-rings are a hybrid of silicone and FKM materials.

Round Clean Room Buna-N O-Rings

Round Clean Room Buna-N O-Rings
These round food-grade O-rings are cleaned and bagged in an ISO Class 7 (10,000) clean room to remove direct, bacteria, and surface particles. Buna-N is suitable for a broad range of fluids including oils, water, and mild chemicals.

Round AC HNBR O-Rings

Round AC HNBR O-Rings
HNBR round O-rings, or highly saturated nitrile, have a temperature range of -25F to +350F. They are used in all oil-resistant sealing applications, including automotive refrigeration systems using freon and in power steering seals using type A fluid.

Round Kalrez 7075 O-Rings

Round Kalrez 7075 O-Rings

Kalrez 7075 round O-rings return to their normal state after being repetitively compressed. These O-rings are durable and withstand hot and cold temperatures and have a glossier finish than other Kalrez models. They are designed for use in the chemical and hydrocarbon processing industries.

Round Internally Lubricated Buna-N O-Rings

Graphite filler serves as an internal lubricant, making for easier installation and reducing wear to extend seal life. These round O-rings do not stick to moving parts and are designed for use in start-stop applications

Round Conductive Silicone O-Rings

Round Conductive Silicone O-Rings
These electrically conductive round O-rings divert static charges away from sensitive equipment. Silicone is resistant to high temperatures.

Round Kalrez 6230 O-Rings

Round Kalrez 6230 O-Rings
Kalrez 6230 is a food- and medical-grade round O-ring useful when high purity is needed. They are made of FDA-listed materials and are 3-A and USP VI certified. Like other Kalrez O-rings, these seals also resist harsh chemicals and extreme temperatures.

Round Metal Detectable Silicone O-Rings
