Panam Instrumentation tube fittings provide a zero leak proof seal which will withstand high pressure, impulse, vibration and temperature.These features offer high safety and maintenance free smooth working. Each component is precision machined to the most accurate tolerance; maintain TQM practices throughout manufacturing process. The fittings are manufactured in accordance with 1509001 quality standards and CE marking requirements with complete traceability records available upon request. Available in 316 55, Brass, CS, Monet materials in a variety of end connections. Straight fittings are machined from bar stock and shaped bodies are machined from forgings. The fittings are used on instrumentation process control systems, analysers and environmental equipment in oil and gas, Petro-chemical. Power generation, Pulp and Paper industry and many more. Assembly Instructions INTRODUCING TWIN FERRULE TUBE COMPRESSION FITTINGS
1
Functions
Compression nutThreads are silver plated which prevents galling. Back Ferrule locks together the fittings and tube forms a primary Seal which absorbs the pressure pulses and vibration. Front Ferrule Forms a secondary seal which connects tube and fitting and guarantees a bubble tight Zero Leak Sealing. Rugged bodyconstruction, high precision machined surface and standardised tolerances provides maximum trouble free service life in severe working conditions.
The above illustrates sealing action of a Tube Fitting assembly which takes place after the assembly is fully tightened

1 Insert the tubing in to the Tube Fitting until it comes up to the tube stop. 2 Ensure that the nut is finger tight and tighten the nut 1-1/4 turns as shown in figure. 3 For 1/8" and 3/16 Fittings only 3/4 turns as shown in Fig-3.
The Metric size of the Fittings have extra stepped shoulder on the body and nut to distinguish them from imperial size. All Dimensions are in mm unless otherwise stated. Dimensions are for reference only, subject to change.
