Technical Specification – Compressed Air System Fittings
Product Selection and Installation
SynergAir Eco Line fittings and related products are specifically designed to Technical Specification and should be selected, installed, used and maintained in accordance with these Technical Specifications. It is the customer’s/user’s responsibility to ensure that SynergAir fittings and related products are suitable for their intended applications, are properly installed and maintained and are used in accordance with the Technical Specifications. It is also the customer’s/user’s responsibility to provide its own customers with all relevant technical information about SynergAir products it supplies them. If you have any questions about our technical specifications, please contact us.
For use with chemicals or other potentially aggressive liquids, please refer to our Customer Services Department.
SynergAir Eco Line fittings and related products are not recommended for use with explosive gases, petroleum spirits, and other fuels or for central heating systems.
SynergAir Eco Line Technical Data – Maintenance and Replacement Intervals
SynergAir Eco Line products generally require little maintenance but as a minimum we recommend routine visual inspection. Frequency of visual inspection will depend on severity of application and risk of failure. If after visual inspection SynergAir Eco Line products appear damaged, cracked, charred, discoloured, heat distorted or corroded they should be replaced. Any product that is or appears to be leaking should be replaced.
Product life is affected by the severity of the application, the hostility of the working environment and contact with aggressive chemicals or liquids. It is therefore important that specific replacement intervals be considered by specifiers/users/customers based on previous service life or when failure could result in unacceptable downtime, damage or injury risk.
SynergAir Eco Line Technical Data – Installation and System Testing
Fittings and tube should be kept clean and undamaged before use.
All tube and fittings installations must be pressure tested after installation to ensure system integrity before handing over to the final user. See also “How to make a connection”.
Working Temperature Range
Minimum Working Temperature = -20°C
Maximum Working Temperature = +70°C
The above is for use with air. For below 0°C please consult our Customer Services Department.
The SynergAir Eco Line Technical Data for Fittings – Compressed Air System is suitable for the following temperatures and pressures.
The above ratings are for air. For use with other fluids or other tube or at other temperatures and pressures, please consult our Customer Services Department.
Eco Line fittings are intended for use with SynergAir aluminum pipe but are also suitable for use with a wide range of plastic and soft metal pipes including UPVC, ABS, Polyethylene, Nylon, mild steel and copper to the tolerances set out below. Soft plastic pipe, such as Nylon should have a minimum wall thickness of 1.5mm. The pipe must have a good quality surface and be damage free.
SynergAir Eco Line fittings are intended for pipes with outside diameters to the following tolerances
|Size||12mm to 28mm OD|
|Tolerance||+0.05 to -0.10mm OD|
Maximum Torque Values
The following maximum torque values should be applied.
It is recommended that all installations are checked prior to use to determine that a seal has been made.
Do not overtighten plastic fittings as this could cause undue stress and eventual failure. Recommended torque figures are shown above and must be adhered to.
Cleaners and Sanitising of Acetal Fittings
Our advice to customers is to use cleaners and sanitising agents that are above ph4 and low in hypochlorite levels. Acetal fittings and parts that are cleaned and/or sanitised should be rinsed immediately with copious amounts of clean tap water to remove all traces of the cleaners.
Details of which products are made from acetal are shown in our catalogues but generally SynergAir Eco Line products incorporating acetal are designated by the part number prefix PI, PM, CI, CM and RM. Polypropylene fittings offer greater resistance to aggressive chemicals than acetal fittings. Polypropylene does not have the same mechanical properties as acetal and polypropylene fittings are generally designated by the part number prefix PP and PPM.
Installations – Our Recommendations
The pressure rating and installation guidelines of the tubing involved must also be considered during the design of a compressed air system.
Pipe should be supported at minimum 800mm to prevent excessive load being applied to the fitting. These supports should not be closer than 25mm from the end of the fitting.
SynergAir Eco Line fittings and pipe should only be connected after the air receiver and not direct to a compressor.
We recommend collet covers be fitted when pipework is hidden inside walls and ceilings.
It is recommended that all pipe and fittings installations are pressure tested after installation and before handing over to the final user.
Whilst we give a warranty against defects in manufacture or materials, it is the responsibility of the specifier to ensure that fittings and related products are suitable for their application. The installation must be carried out correctly in accordance with our recommendations, complying with recognised codes of practice and relevant national standards, and be properly maintained. Please refer to our terms and conditions of sale.
The company has a policy of continuous research and development and reserves the right to amend without notice the specification and design of all products. SynergAir reserves the right to change the colour and shape of products. Photographs are for illustration purposes only.
