HOW TO SELECT O-RINGS. O-Ring selection is based on the chemical compatibility, application temperature, sealing pressure, lubrication requirements, quality, quantity and cost. That, combined with long list of materials from which you can chose from, plus the thousands of sizes—as well as numerous specifications specific to certain uses (aerospace, military, etc.) means that there are many thousands of possible combinations. Large manufactures and distributors claim as many as 14,000 individual SKUs and tens of million unit in stock. We have 35,423 SKUs listed online and about 50 million o-rings in stock. However, from the buyers point of view, the basic selection process would start with the following considerations in purchasing an o-ring.

  • O-Ring Size (inch or metric) - Cross Section ( thickness ) X Inside Diameter.
  • Temperature of product being sealed.
  • Application or type of equipment. Is the seal dynamic or static?
  • Material being sealed (solvent, acid, caustic, chemical compatibility)
  • Operating pressure - Durometer Rating

With this o-ring information we can assist you in finding an o-ring that matches your needs, via phone, email or live online chat. An additional consideration is compliance with use standards and specification such as have be established by the military, drinking water, food processing, aerospace, pharmaceutical, etc.

O-Rings and Seals are very important to us and as part of our effort to "Make getting o-rings easy!", we have improved several areas of our business for 2020 and beyond. We needed more space for our expanding inventory so we added and additional 5,000 square foot warehouse space. We added several key people, Gary in our sales department, Savanna and Macey to our warehouse crew, Julian in our kit department and Steven to assist in the O-Ring Vulcanizing department. ISO Certification is underway and Melissa should have it completed early in 2020. Shipping department is reducing costs and increasing service by adding a defualt 2-Day Air Shipping Service for as low as $6.99. We make getting o-rings easy!

As a family-owned business we enter our 13th year of business in 2020 with great excitement. We have added additional inventory, product offering and great new staff members that not only make it easier to get o-rings, but for us it makes it great to come to work. Our plan is to continue adding new product and services to enhance our current offerings. Adding The O-Ring Store LLC as your O-Ring and seal supplier will improve your ability to repair or build your products and service. We know how hard it is just to get the product you need, by having a shop account and registering you will receive the appropriate business discounts, permanent cart, address book, and order history.
