Currently no specific test can be provided as a precise estimate of the expected lifetime of the elastomeric gaskets. Fra.Bo provides orings which have positively passed all the tests related to the relevant European Standards whose strictness can be taken as a warrant for quality and durability.

Absolutely not: this will lead to a loss of validity of the warranty and may be dangerous or unsafe.

As a general rule suitability of the frabopress pressfittings (Copper/Bronze, Stainless Steel and C-Steel) for this application is related to the oil content of the compressed air. In case the oil quantity is below 5mg/m³ any of said systems can be used as supplied.

In case the oil quantity is over said threshold we require the oring to be changed with the red FKM oring which features a unique resistance to oils, mineral greases thus granting higher performances.

Maximum operating pressure is, in any case, 16bar.

Please avoid the build of condensate inside the C-Steel sytems using dry air.

Frabopress fittings are manufactured using high quality materials and components and are specifically designed to stand the test of time. A pipe run made using the FRABOPRESS products (fittings and connecting pipes) which is installed with the prescribed tools and according the installing instruction has an expected lifetime of 30 years (this is not a legal binding warranty).

Legal warranties follow the legal prescriptions.

Yes, for sure. The black EPDM O-Ring which is commonly installed in FRABOPRESS V, C-STEEL and 316 series is suitable for said application.

Not much: those are two different German and English names for the same compound.

Any operation which may eventually lead to thermal stress is not recommended for pressfittings systems due to the presence of O-Rings.

If welding is required please take into consideration due cooling techniques which may help in keeping the temperatures under control.

Press fitting production refers to UNI 11065 standard for copper fittings or copper alloy fittings and to UNI 11179 standard for steel fittings. The compliance with these standards is an essential requirement for using the fittings in a plant.

Design and installation of press fitting systems must comply with local standards, standards defined by the current state of the art and the standards described in the technical manual of the specific product.
