Working Pressure and Temperature Range Super Speedfit fittings are suitable for the following pressures and temperatures.
Also suitable for vacuum Depending on the tube used, under certain conditions fittings may be used at higher pressures and temperatures. Please refer to our Customer Services Department for guidance. Note 1 Bar = 14.5 PSIG. Tube Types Plastic Tube — Polyethylene, nylon, and polyurethane conforming to the tolerances shown below. For soft tubing or thin wall tube we recommend the use of tube inserts. Braided Tube — Use of Tube to Hose Stems is essential when using braided tube or hose. Use of clamps to retain braided tube on barbs is recommended. Metal Tube (soft) — Brass, copper, or mild steel conforming to the tolerances below. Metal Tube (hard) — We do not recommend Super Speedfit fittings for hard metal tubes or chrome plated tubes. For stainless steel and other polished metal tubes we recommend the use of Superseal fittings. Click here for more details. It is essential that outside diameters be free from score marks and that the tube be deburred before inserting the fitting. Tube Tolerances Super Speedfit fittings are offered for tubes with outside diameters to the following tolerances.
Collet Covers Are available as additional security against removal of the tube or to provide a simple means of color coding. The cover is offered in a range of six colors (black, red, yellow, gray, blue, green). Please refer to our Customer Services Department. Food Quality All fittings are produced in Food and Drug Administration (FDA) approved materials and are therefore recommended for food quality applications. |
Installation and System Testing
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." Chemicals For use with chemicals or other potentially aggressive liquids, please refer to our Customer Services Department. Super Speedfit fittings are not recommended for use with explosive gases, petroleum spirits, and other fuels or for central heating systems. Maximum Torque Values for Threaded Fittings
a. Manufacturer recommends that OEM customers consider replacing threaded ports with the more modern Cartridge Systems b. It is recommended that all installations are checked prior to use to determine that a seal has been made. c. The maximum torque figures quoted for use with Speedfit fittings are dependent on the mating thread conforming to the relevant US, British or International thread standard. Maintenance and Replacement Intervals Generally, little maintenance is required, 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 products appear damaged, cracked, charred, discolored, 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. Cleaning and Sanitizing Our advice to customers is to use cleaners and sanitizing agents that are above pH 4 and low in hypochlorite level. Acetal fittings and parts that are cleaned and/or sanitized should be rinsed immediately with copious amounts of clean tap water to remove all traces of the cleaners. ECOLAB Oasis 133 is recommended as a suitable external cleaner for acetal products. Polypropylene fittings offer greater resistance to aggressive chemicals than acetal fittings. Polypropylene does not have the same mechanical properties as acetal. |
