In oil & gas, chemical processing, and analytical instrumentation, a leak isn't an inconvenience - it's a safety event, a compliance breach, or a contaminated sample. Parker instrumentation tube fittings, manifolds, and valves are engineered for the kind of work where 'good enough' isn't.
Parker SS Tubing & Tube Fittings (CPI™ single-ferrule)
Parker CPI™ single ferrule compression tube fittings are designed as leak free connections for process, power, and instrumentation applications.
Parker Instrumentation Valves (needle, ball, check, manifold)
Parker offers the most comprehensive range of instrumentation valves in the Industry. These high quality valves perform in system pressures up to 150,000 psi. Innovative performance designs are available in all of our needle valves, ball valves, check valves, relief valves, metering valves, block and bleed valves, stream switching valves, and control valves. We offer these instrumentation valves in multiple configurations, end connection sizes and a variety of materials. Parker has the instrumentation valve to meet your system’s specific application.
Parker Solenoid Valves
Parker’s range of solenoid valve includes types and configurations for a wide variety of hydraulic, pneumatic, instrumentation, medical, refrigeration and aerospace applications. Solenoid valve solutions from Parker offer reliability, fast and safe switching and compact designs suitable for challenging environments.
Parker Miniature Solenoid Valves
Parker’s range of solenoid valve includes types and configurations for a wide variety of hydraulic, pneumatic, instrumentation, medical, refrigeration and aerospace applications. Solenoid valve solutions from Parker offer reliability, fast and safe switching and compact designs suitable for challenging environments.
Parker Miniature Proportional Valves
The VSO® Low Flow valve provides enhanced flow control for applications where precise control flow control is required between 0 - 500 sccm
Parker Miniature Pumps
Parker’s miniature air gas/liquid diaphragm pump line provides the highest flow per Watt available on the market. Parker’s miniature pumps are suited for applications ranging from portable battery powered devices, such as air sampling, to laboratory and medical instrumentation. Parker also offers a full line of miniature liquid diaphragm pumps which have a higher fluidic resistance compared to gas or air due to being incompressible and of a much higher viscosity. Parker’s miniature diaphragm pumps provide customers with substantial cost savings and reduced field service time.
PET Bottle Valves
PET Bottle Valves used for PET bottles are specialized components in the bottling industry, primarily for blow molding and filling processes
Why Specify Parker Instrumentation
CPI™ single-ferrule design
Parker's CPI fittings deliver leak-free, gas-tight connections with simple installation and lower assembly torque than dual-ferrule alternatives.

Frequently Asked Questions
Parker CPI™ uses a single, dual-action ferrule that grips the tube and seals simultaneously - delivering leak-free performance with fewer parts, lower assembly torque, and faster installation than traditional twin-ferrule designs.
Parker A-LOK twin-ferrule fittings are dimensionally interchangeable with most major twin-ferrule brands at the gauge level. Full mixing of components is not recommended; we can advise on specific compatibility.
Yes. Parker offers a comprehensive range of instrumentation valves and tube fittings certified to NACE MR0175 / ISO 15156 for use in sour gas and oilfield environments.
We stock Parker 316 SS instrumentation tubing in metric sizes from 3mm to 38mm OD and imperial sizes from 1/8" to 1.5" OD, in standard and heavy wall thicknesses.
Yes. We supply Parker's miniature solenoid valves, miniature proportional valves, and miniature pumps used in clinical diagnostics, mass spectrometry, and other precision analytical instruments.
