A permanent weld-type tube fitting which provide a sturdy, tight integral line system that remains unaffected by shock, vibration or thermal distortion. Ideal for use in the chemical industry, utility field, or nuclear power plants which demands the utmost in reliability.

Push-to-connect fittings have stainless steel grab rings eliminating the need for tube supports when using Urethane tubing. Parker Prestolok II offers a polymer body for a economical alternative in pneumatic applications that do not require the higher pressure capacity of standard Prestolok fittings.

INSTRUMENT PIPE FITTINGS -

Precision Pipe Fittings designed for process control and instrumentation connections between pipe size and/or tube sizes:

features:

• All pipe threads are National Pipe Taper (NPT)
• Rolled male threads for extra strength
• Size range from 1/16" through 1" NPT
• Working pressures calculated in accordance with Power Piping Code ANSI B31.1 and Refinery Pipe Code ANSI B31.3
• Materials: 316 stainless steel, brass and steel. Other materials by special order

The Compressed Gas Association (CGA) has established and maintains a standardized set of valve outlet and inlet connections to help minimize the possibility of hazardous misconnections of incompatible gases. Ewal Cylinder Connections provide ultra high integrity CGA, DIN, JIS and British standard cylinder connections including: nipples, nuts, gaskets, adapters, caps, and plugs

PFA FITTINGS FOR SEVERE SERVICE -

Parker’s durable PFA fittings have been engineered to be leak-free in pressure applications (0-120 psi). The all wetted surfaces are of chemically inert corrosion resistant PFA Teflon. Typical applications for Teflon products include semiconductor manufacturing, chemical, food, pharmaceutical processing, and biomedical and analytical instrumentation.
