Engineering Services
Technical support for O-ring material selection, groove design, failure analysis and custom seal development.
We are not just an O-ring supplier. Our engineering team works directly with design engineers, quality managers and procurement teams to solve sealing problems before they reach production. Whether you need a material recommendation, a groove design review, or root-cause analysis of a field failure, we provide practical engineering support at no extra cost.
What We Offer
Material Selection
Choosing the wrong elastomer is the leading cause of premature seal failure. We review your operating temperature, fluid media, pressure and dynamic conditions to recommend the most cost-effective material that will perform reliably. We support NBR, HNBR, FKM, EPDM, VMQ, PTFE and FFKM grades.
Groove Design Review
Proper gland geometry is as important as the O-ring itself. We review your groove width, depth, corner radii, surface finish and clearance gaps to verify compression rate, gland fill and anti-extrusion requirements. Recommendations are provided in dimensioned sketches or marked-up drawings.
Failure Analysis
When a seal fails in the field, we help identify the root cause through visual inspection, dimensional measurement and operating history review. Common failure modes include compression set, extrusion, spiral failure, chemical attack and thermal degradation.
Custom Size Development
Non-standard dimensions are our specialty. We manufacture custom inner diameters and cross sections with no tooling charge for standard profiles. Send us your drawing or sample and we will confirm feasibility, tolerance capability and lead time within 24 hours.
Sample & Prototype Support
Order as few as one piece for testing and validation. We support prototype builds, PPAP documentation, and first-article inspection for automotive, aerospace and medical device programs.
Standards Compliance
We manufacture to AS568, ISO 3601, DIN 3771, JIS B 2401 and customer-specific standards. Material certifications include ISO 9001, RoHS, REACH and FDA compliance documentation.

Is there a charge for engineering support?
No. Material selection guidance, groove design review and failure analysis are provided free of charge to all customers and prospective customers.
How quickly can you review a drawing?
Most drawings and technical enquiries are reviewed within 24 hours. Complex failure analyses or multi-material evaluations may take 48 hours.
Can you sign an NDA?
Yes. We routinely sign non-disclosure agreements before receiving proprietary drawings, application data or failure samples.
Do you provide PPAP documentation?
Yes. We support automotive PPAP levels 1-5, including material certifications, dimensional reports, process flow diagrams and control plans.
Can you analyse a failed seal we send you?
Yes. Send the failed seal and a brief description of the operating conditions. We will inspect it, identify the failure mode, and recommend a solution.
