Seals Maintenance Guidelines
To ensure optimal performance and longevity of your seals:
- Inspect seals regularly for wear, cracking, or deformation
- Lubricate with compatible grease during installation
- Store in cool, dry conditions away from direct sunlight
- Use proper installation tools to prevent damage
- Replace seals at recommended service intervals
Seals FAQ Section
Q: How do I select the right seal material for my application?
A: The ideal seal material depends on your operating conditions. For general industrial use, nitrile (NBR) offers good oil resistance at moderate temperatures. For high-temperature applications above 400°F, Viton (FKM) is recommended. Chemical exposure requires careful material selection - consult our technical team for specific chemical compatibility charts.
Q: What causes premature seal failure?
A: Common causes include improper installation (45% of failures), excessive pressure (25%), incorrect material selection (15%), contamination (10%), and improper storage (5%). Using high-quality seals with proper installation techniques significantly reduces failure rates.

| Oil & Gas | Chemical-resistant seals | API compliance |
Seals FAQ Section
Q: What's the difference between static and dynamic seals?
A: Static seals are designed for applications without relative movement between mating surfaces (flange gaskets, O-rings in housings). Dynamic seals accommodate motion - including reciprocating (hydraulic piston seals), rotary (shaft seals), and oscillating movements. Dynamic seals require special materials and designs to handle friction and wear.
Q: How long do seals typically last?
A: Seal lifespan varies by application. Under ideal conditions: O-rings last 3-5 years, hydraulic seals 1-3 years with proper maintenance, and rotary shaft seals typically 10,000-50,000 operating hours. Factors affecting longevity include temperature extremes, pressure cycling, chemical exposure, and surface finish of mating components.
Custom Seals Solutions
Our engineering team can develop custom seals for specialized applications:
- Non-standard sizes and cross-sections
- Multi-material composite seals
- Specialized coatings and surface treatments
- Prototype-to-production services
Seals Selection Guide
Follow these steps to choose the perfect seal:
- Identify the sealing environment (fluid, temperature, pressure)
- Determine the type of motion (static, reciprocating, rotary)
- Select appropriate material based on chemical exposure
- Choose seal design that matches your groove/space constraints
- Consider installation requirements and maintenance access
Seals FAQ Section
Q: Can seals be repaired or must they always be replaced?
A: Seals are generally replacement items rather than repairable components. Attempting to repair damaged seals typically compromises performance and safety. Some specialized industrial applications use seal repair techniques, but for most standard applications, complete replacement with new seals is the recommended approach for maintaining system integrity.
Q: What certifications do your seals have?
A: Our seals meet numerous international standards including ISO 9001:2015, API 6A, ASTM D2000, FDA 21 CFR 177.2600 (for food-grade applications), and RoHS compliance. Military specifications (MIL-SPEC) and aerospace certifications (AS9100) are available for specialized product lines. Certificates of compliance are provided with all shipments.
