Overview
SUPERLOK compression fittings provide high-integrity, metal-to-metal tube connections designed for leak-free performance in instrumentation, hydraulic, pneumatic, and high-purity process systems. Manufactured with precision ferrule technology, these fittings ensure vibration resistance, dimensional consistency, and repeatable sealing without the need for pipe threading, welding, or sealants.
SUPERLOK delivers exact tolerances and uniform ferrule geometry, enabling consistent tube grip, controlled deformation, and secure mechanical engagement. Their double-ferrule sealing system allows secure operation under high pressure, thermal cycling, and mechanical vibration.
Engineers choose SUPERLOK for high-accuracy instrumentation panels, chemical dosing skids, fuel systems, hydraulic controls, and clean-room assemblies where connection failure is unacceptable.
Field technicians benefit from easy installation, reusability, and the ability to maintain tubing systems without cutting, rewelding, or rethreading lines.
Makers and advanced hobbyists rely on SUPERLOK for precision CNC coolant lines, pressure prototypes, lab experiments, and fluid routing in technical workshop builds.

Technical
SUPERLOK utilizes precision double-ferrule compression sealing. The front ferrule provides metal-to-metal sealing while the back ferrule delivers tube grip and mechanical stability.
Fittings are typically produced from 316 stainless steel to support corrosion resistance, chloride stability, and chemical compatibility under high-purity conditions.
Manufactured to meet or exceed ASME, ASTM, and ISO standards governing compression fitting performance, SUPERLOK fittings ensure uniform tolerances and predictable makeup torque across all sizes.
The fittings maintain sealing integrity under thermal cycling, pressure pulses, and high-frequency mechanical vibration common in hydraulic and instrumentation environments.
SUPERLOK’s ferrule design prevents galling, over-compression, and loss of holding strength, supporting long-term durability in harsh industrial environments.
Applications
SUPERLOK compression fittings are used in high-performance fluid and gas systems where leak integrity, vibration resistance, and dimensional accuracy are essential.
Instrumentation engineers use SUPERLOK fittings for pressure transmitters, flow meters, analyzers, sampling lines, and panel-mounted equipment.
Chemical processing facilities depend on SUPERLOK for reagent injection lines, corrosion-resistant sample loops, and chemical dosing circuits.
Fuel and energy systems use SUPERLOK for clean, vibration-resistant connections in diesel, natural gas, hydrogen, and biofuel lines.
Makers use these fittings in laser cooling systems, high-pressure bench rigs, prototype fluid networks, lab test setups, and robotics subsystems requiring precise fluid routing.
