A-LOK Tube Fittings from Parker

Fluid Controls is proud to supply Parker’s A-LOK two ferrule compression tube fittings. These highly configurable tube fittings provide exceptional leak-free connections and come in a wide range of sizes and corrosion resistant materials.

What are A-LOK tube fittings?

Parker’s A-LOK tube fittings are designed to provide reliable leak-free connections for instrumentation, process and control, and analyser applications. Manufactured to the highest quality standards, these tubefittings are available in a broad range of sizes, corrosion resistant materials and configurations.

Instrumentation tube fittings
As standard, the tube fittings manufacturer’s A-LOK range is manufactured from heat code traceable 316 stainless steel. Other materials include 6Mo, Alloy 825, Alloy 625 and Alloy C-276. Straight fittings are machined from cold finished bar stock, while shaped bodies are machined from close grain forgings.

The tube fittings are available for imperial tube sizes from 1/16” through to 2” O.D., and for metric sizes from 2 mm through to 25 mm O.D.

Features and benefits of A-LOK instrumentation tube fittings

All Parker A-LOK fittings use an advanced two ferrule system for reliability and ease of assembly and disassembly. No special tools are required and the design ensures that all make and remake motion is transmitted axially to the tubing.

There is no radial movement to stress the tubing, so its mechanical integrity is uncompromised. The fittings’ back ferrule is hardened by Parker’s innovative Suparcase™ surface treatment process which – unlike many competitive hardening processes – actually increases its corrosion resistance.

An exceptionally wide choice of configuration styles includes:

  • Tube to male pipe.
  • Tube to female pipe.
  • Tube to tube unions.
  • Port connectors.
  • 37˚ flare (AN) to A-LOK.
  • Tube to O-ring seal.
  • Tube to welded systems.
  • Analytical fittings.
  • Barbed fittings.
