Rocket Seals has been a leading supplier of quad rings or X-rings for industrial applications. We stock an extensive inventory of quad rings from leading manufacturers and can provide the quad ring you need for your application. We service a wide range of industries, including, aerospace, military, water treatment, wastewater and filtration, medical and life sciences, oil and gas, power generation, chemical processing, and original equipment manufacturers.

We are committed to offering superior customer service from your first call through the delivery of your order. We partner with our customers – providing you with technical expertise when selecting the quad or X-ring that best meets your specifications, quality assurance, and fast turnaround. Our customers include facilities and maintenance management and distributors sourcing replacement parts and OEMs sourcing quad rings for an existing product or a new product.

Quad rings and X-rings have a four-lobed design that provides double the sealing surface of standard or square cut O-Rings. A square cut O-Ring was used first but is being replaced by the quad ring or X-ring. As a result of the four-lobed design, the seal is stronger and is better at preventing leaks.  

Our extensive inventory of quad rings is available in a wide range of standard and metric sizes in Buna, FKM and special materials. We offer quantities from small order to production runs and assemblies. We can supply quad rings with material and manufacturing processes certifications if required for your application. We offer same-day shipping, custom kits, and follow strict QA/QC protocols for every order so you know that your critical parts will arrive on-time and be exactly what you ordered.

At Rocket Seals, our commitment to the highest standard of customer service includes technical support to assist you in selecting the quad ring that will meet your application requirements. If your application requires unique or hard-to-find sizes, shapes, or materials, we will work with our manufacturing partners to source the quad rings you need.

O-Rings Product Colors

Special order O-rings and seals in different colors are increasingly popular with OEMs for parts identification and are priceless if assembly or repair mistakes are avoided.  Please call Rocket for specific information (lead times, minimums) about both custom colors and stock colors for your production or private labeled repair kits.
