Swagelok® Fittings
Swagelok® Fittings That Drop Into Your Existing System Without Modification
Building or repairing a fluid line means matching every dimensional spec at every process connection. Our tube fittings are machined to the same OD tolerances, ferrule geometry, and thread standards as Swagelok® parts. Run our compression hardware alongside Swagelok® in the same manifold. The connection is clean. The seal holds.
Tube Stub-Out Length and Ferrule Seat Geometry Match Swagelok® Dimensional Data
- Ferrule seat angle machined to match Swagelok® front ferrule contact geometry specification
- Tube stub-out dimension verified against Swagelok® published dimensional data
- Back ferrule hinge depth produces correct load distribution across the front ferrule face
- Metal-to-metal seal achieved at 1.25 turns from finger-tight across all OD sizes
- Available in 1/16" through 1" tube outside diameter, inch and metric configurations
Port Body Dimensions Allow Direct Manifold Swap Without Re-Engineering
These components are safe to combine with existing Swagelok® hardware, so you replace what failed without touching the rest of the line.
- NPT body threads machined to ASME B1.20.1 for correct taper and seal in existing port hardware
- Face-to-face body lengths match Swagelok® specs for direct manifold panel drop-in
- Body OD dimensions verified for correct clearance in close-tolerance panel cutouts
- Available in male connectors, female connectors, bulkheads, union elbows, and tee bodies
- Part number cross-reference covers Swagelok®, Parker, Ham-Let, Hy-Lok, and DK-Lok hardware

Corrosion-Matched 316 SS Prevents Galvanic Attack Across Your Entire Line
- Body, nut, and ferrule set all machined from 316 SS to eliminate mixed-metal galvanic paths
- Heat codes stamped on every body for traceability from production batch to installed location
- 316 SS resists chloride pitting, crevice corrosion, and sour gas attack in harsh process service
- Hastelloy C-276 available for highly corrosive acid and high-chloride process environments
- NACE MR0175 compliant alloy options for sour gas and H₂S service applications
If you are also standardizing on 316 SS for the valve side of your system, our needle valves and ball valves carry the same alloy and the same heat code traceability.
ISO 9001 Controlled Manufacturing and Independent Testing Validate Every Part
- ISO 9001 certified manufacturing with documented process controls on every production run
- Independent hydrostatic burst testing to 1.5x working pressure per product family
- NACE MR0175 compliance for sour gas, H₂S, and acidic process environments
- Axial pull-out force verified to exceed tube tensile strength at rated working pressure
- Full material test reports and third-party certifications available on request

What Engineers Ask Before Switching
Get answers to the most common questions about making the switch to Superlok USA.
Are these actually interchangeable with Swagelok® parts?
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.
Will using alternatives void my OEM equipment warranties?
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.
What if a part doesn't fit or match specifications?
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.
Who else is using SuperlokUSA as Swagelok® alternatives?
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.
Why are your prices lower if the quality is the same?
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.
Do you provide engineering support before I order?
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.
