Request O-Ring Samples

Validate material compatibility, dimensional fit, and compression set before placing a production order.

Sampling is the fastest way to de-risk a sealing project. We supply material sample sets and custom-size prototypes in NBR, FKM, EPDM, VMQ (Silicone), PTFE and FFKM. Most sample requests ship within 3-5 business days.

Why Request Samples?

Material Validation

Test the O-ring in your actual fluid, temperature, and pressure conditions before committing to a production quantity.

Dimensional Fit Check

Verify groove interference, stretch, and compression rate with physical samples rather than theoretical calculations.

Fast Turnaround

Standard samples ship in 3-5 days. Custom prototypes typically ship in 5-7 days.

Engineering Support

Our team reviews your application details and recommends the best material grade and hardness for your test.

Sample Types

Material Sample Set

Receive a small assortment of NBR, FKM, EPDM and Silicone O-rings for visual inspection and basic compatibility screening.

Turnaround: 3-5 days

Custom Size Prototype

Submit your drawing or target dimensions and we will produce 5-10 pieces for groove-fit validation.

Turnaround: 5-7 days

Application-Matched Sample

We select the exact compound, hardness, and color used in your target application and ship test pieces with a datasheet.

Turnaround: 5-7 days

Frequently Asked Questions

Are samples really free?

Standard material sample sets are free of charge for qualified engineering and procurement contacts. You only pay for shipping. Custom prototypes may incur a small tooling fee depending on complexity.

How many pieces are included in a sample set?

A typical material set includes 2-3 pieces each of NBR, FKM, EPDM and Silicone in a common size such as AS568-214. Custom prototypes are usually 5-10 pieces.

Can I request a specific compound or color?

Yes. Include your requirements in the application field and we will match the compound, hardness, and color as closely as possible.

How long does shipping take?

Samples ship via DHL or FedEx Express. Transit time is typically 3-5 days to North America and Europe, and 1-3 days within Asia.
