Frequently Asked Questions (FAQs)

#

What are the main reasons for using custom o-rings?

You might need custom o-rings if standard sizes or materials don’t fit your specific application. This could be due to unique size requirements, special material needs, or the need for low friction properties.

#

How do I choose the right material for my custom o-ring?

When selecting a material, consider the conditions your o-ring will face, such as temperature, chemical exposure, and pressure. Popular materials include FFKM for high-temperature and chemical resistance, EPDM for heat and steam resistance, and PTFE for its chemical inertness.

#

What are the different manufacturing methods for custom o-rings?

Custom o-rings can be made using various methods, including compression molding for high volumes, continuous molding for large or dynamic applications without tooling costs, and vulcanization for quick turnaround times and static conditions.

#

How important is sizing when it comes to custom o-rings?

Sizing is crucial. You need to determine the gland measurements and ensure the o-ring fits snugly without excessive stretch (more than 5%). Proper sizing prevents leaks and ensures the o-ring’s longevity.

#

Can custom o-rings solve specific sealing problems in my application?

Yes, custom o-rings can resolve sealing issues that standard o-rings can’t. For example, using a softer material can help seal porous surfaces, and special compounds can reduce friction in dynamic applications.
