Parker's Hydraulic Quick Couplings have a wide variety of designs, some of which are tailored to a particular application or use.  Based on the valving, hydraulic couplings can be either double shut-off or straight-through.  Double shut-off couplings have valves in both halves (coupler and nipple) keeping fluid loss to a minimum.  Straight-through couplings have no valves and are ideal for high flow with low pressure drop. 

Parker's Instrumentation Quick Couplings are for use in the process, power, and instrumentation fields.  Applications include equipment relative to chemical processing, chemical refining, medical, process control, and semiconductor production.

Parker's Pneumatic Quick Couplings are single shut-off quick disconnects available in several interchange designs.  Coupler styles are manual connect, push-to-connect, and safety exhaust.

Thermoplastic Couplings offer push-to-connect operation, light weight design, and excellent chemical compatibility to meet a broad range of applications.

PF Series are non-spill couplings designed for use in closed system transfer and dispensing of chemicals with minimal environmental contamination.  Available in body sizes 1/2" through 2".

PPM, PPL and PPA Series  are general purpose, thermoplastic couplings with push button operation.  Available in body sizes 1/8" and 1/4".

Spectrum Series couplings are available valved or un-valved and in an optional panel-mount configuration.  Available in body sizes 1/8" and 3/8".

Diagnostics - A Wise Investment

When time is money... In today's "Lean Manufacturing" environment there is more emphasis put on increased production and reduced downtime than ever before.  You can't afford to have your equipment sitting idle.  Momentary pressure spikes and flow surges that are not recognized by other conventional mechanical measuring devices can unexpectedly destroy both components and systems.

An ounce of prevention... Diagnosing a problem before it occurs should be your primary objective.  Whether it is a piece of mobile construction equipment, or an automated industrial assembly machine, lost production is lost profits.  The basic prescription for system maintenance is prevention.

Hydraulic and Pneumatic... Parker's SensoControl product line is a valuable tool for diagnosing problems both before and after they occur.  Today's hydraulic and pneumatic systems are continuously becoming more sophisticated.  Being able to identify critical information for optimizing machine efficiencies is a necessity.

Parker's SensoControl Industrial Sensors are ideal for permanent installation in industrial and mobile hydraulic applications where continuous system monitoring is needed. These precision engineered sensors are rugged in construction and deliver a high degree of dependability and performance with superb stability and resistance to interference.

SensoControl Industrial Controllers combine all of the functions of mechanical sensors, switches, and displays into a single intelligent instrument. These simple, robust solutions will accurately regulate the critical operating parameters (pressure, temperature, and tank level) for hydraulic and pneumatic systems.
