Get answers to the most common questions about making the switch to Superlok USA.
Yes. Our components are engineered to match Swagelok® dimensional specifications, pressure ratings, and material standards. They install directly into existing systems with no modifications required. We manufacture to the same ASTM and ASME standards, ensuring thread compatibility, seal integrity, and pressure performance.
No. Fluid system components are not typically covered under equipment warranties, and using industry-standard interchangeable parts does not void OEM coverage. Our parts meet or exceed the same material and performance specifications. If you have specific warranty concerns, we can provide certification documentation for your records.
We guarantee fit and function. If a cross-referenced part doesn’t match your system specifications, we’ll replace it at no charge or provide a full refund. Our technical team verifies compatibility before shipment, and we maintain detailed cross-reference documentation for every part number.
Our components are used daily in midstream oil & gas facilities, chemical processing plants, pharmaceutical manufacturing, power generation, and semiconductor fabrication. We serve Fortune 500 companies and regional operators alike. Over 500+ facilities nationwide rely on our parts for critical fluid systems.
We don’t charge brand premiums. Our pricing reflects manufacturing cost plus a reasonable margin – not decades of brand positioning. We also maintain direct relationships with mills and distributors, eliminating middleman markups. Same certifications, same performance, transparent pricing.
Absolutely. Our technical team can verify cross-compatibility, recommend alternatives for discontinued parts, and provide material certifications before shipment. We’re not just a parts supplier – we’re a technical resource. Call us at (805) 658-2044 or submit your part numbers for verification.
