Swagelok® Quick Connect fittings by Superlok
Swagelok® quick connect fittings are common in systems that demand fast access and clean sealing but when you need an alternative that performs just as well, integrates cleanly, and gives you more control over sourcing, Superlok is the move.
SuperlokUSA® quick connect fittings offer the same push-to-connect convenience as Swagelok® QTM and QC series with options for valved and unvalved connections, panel-mount bodies, and NPT or compression tube ends. These fittings are engineered for reliable shutoff, leak-free sealing, and fast disconnection, making them ideal for use in pressure systems, sampling setups, and mobile test equipment.
Made from 316 stainless steel and other corrosion-resistant alloys, Superlok quick connects are compatible with sanitary stainless steel fittings and designed to handle frequent cycling, exposure to aggressive media, and tight spatial installs. Their robust sealing system supports high-integrity applications in hygienic fluid processors, clean in place instrumentation, and light industrial gas or liquid transfer.
Whether you’re maintaining precise fluid control in a panel build or routing process gases through quick-change analyzer loops, Superlok delivers the same form, fit, and function with cleaner availability and no compromise in spec. Every fitting is leak-tested, dimensionally matched, and supported by technical documentation giving you confidence whether you’re building new or swapping out legacy parts.
Swagelok® Alternate Parts Near
SuperlokUSA quick connect fittings are fully interchangeable with Swagelok and Parker equivalents. Designed to match form, fit, and function, Superlok’s quick connect couplings use the same push-to-connect body dimensions and thread specs, allowing seamless integration into existing fluid and gas systems without modification.
Thread tolerances are held to ASME B1.1 standards, with nut and body threads machined to the same strict dimensional controls used by legacy Swagelok fittings. Every unit is tested for leak integrity and sealing performance to ensure a consistent make-up each time.
A certified SGS intermix-ability and interchangeability burst-test report is available on request, verifying cross-compatibility in pressure systems, pneumatic networks, clean in place instrumentation, and precise fluid control setups.
Installation & Maintenance Best Practices
Superlok quick connect fittings prioritize sleeve lubrication during coupling to ensure snap-fit in portable hose assemblies. Apply silicone grease to O-ring grooves for 316 stainless steel couplers achieving random roughness average (Ra) under 30 micro-inches for dust-free engagement. Align insert with coupler body using guide pins for 0.005-inch clearance, preventing partial insertion that causes leaks in mobile setups.
- Couple by pushing insert fully to click, verifying lock with tug test under 50 lbs, disengaging by sleeve retract in pressure systems to avoid hose whip.
- For high-purity fluid processors, fit with check valves in inserts, adding clean-in-place (CIP) caps for 200°F autoclave cycles that sterilize without O-ring swap.
- Secure hoses with band clamps every 10 inches to resist pull-out, air-testing at 1.5 times maximum allowable working pressure (MAWP) for 5 minutes to spot connection weeps.
- Inspect annually in wash stations for O-ring cracks and sleeve polish with felt wheels, followed by ultrasonic soak at 140°F and steam passivation for corrosion-resistant alloys renewal.
- Re-grease post-250°F, profiling disconnect force with pull testers for precise fluid control retention.
- Log connection cycles and leak events in handheld scanners, scaling to hose lengths for predictive seal changes in field kits.
- For compressed air, add filters upstream, capping flow to 20 scfm to meet CGA V-1 standards in tool changers.
These habits sustain quick connects to 20,000 mates, speeding swaps in assembly lines and medical carts. Scanner data reduces failures 33%. Seal bedding and tugging ensure secure, fast coupling with our quick connect fittings.
Quality & Standards Compliance
Superlok quick connect fittings extrude from 316 stainless steel per ASTM (American Society for Testing and Materials) A479, yielding over 60 ksi (thousands of pounds per square inch) and elongation above 35% for coupler toughness under mating forces. O-ring groove machining conforms to ISO (International Organization for Standardization) 16028 tolerances of ±0.0006 inches on depth, measured by coordinate measuring machine (CMM) for compression ratios of 20-30% to ensure leak-free performance at 1.5 times rated working pressure (RWP).
- Mating testing per SAE (Society of Automotive Engineers) J609 employs compressed air for retention forces above 150 lbs, enduring 15,000 disconnect cycles without pop-out failures to simulate repeated field engagements.
- Sleeve spring fabrication per ASTM A313 from Inconel alloy, with finite element analysis (FEA) modeling insert pull-out at 300 psi (pounds per square inch) for optimized detent reliability under dynamic loads.
- Proof testing at 3 times RWP, serialized in mill test reports (MTRs) with visual non-destructive testing (NDT) for groove flaws under 0.0004 inches, per CGA (Compressed Gas Association) E-4 standards.
- Humidity exposure per ASTM D2247 at 95% relative humidity (RH) shows no swell or degradation, while impact per ASTM D256 confirms lever arm toughness exceeding 50 ft-lbs (foot-pounds).
- SGS third-party reviews include groove profiling and penetrant testing (PT) NDT for uniformity below 0.0005 inches, issuing certificates of compliance (CoCs) under ISO 9001:2015.
This framework produces components for 15-year service in pneumatic carts and mobile connections, surpassing standards for secure coupling in pressure systems with our quick connect fittings.
