Corroflon Hose Assemblies - Corroflon is custom built to individual order and is supplied in the form of finished hose assemblies after the length, liner, braid and end fittings have been decided upon.
Selecting the Hose Grade - The basic grade of Corroflon is Corroflon GP,SS. In many cases, however, one of more of the alternative design options shown on the following pages are incorporated in order to 'custom build' a hose. A hose grade is specified by using the abbreviations given. For example, a hose, which requires a general purpose, anti static liner, with a polymer braid would be designated Corroflon GP,AS,PB
Selecting the End Fittings - Corroflon is available with a range of standard end fittings, both integrally PTFE lined and non lined, which are described on the section labelled end fittings. These fittings may be applied to any grade of Corroflon hose, with either the same or different end fittings at each end of the hose assembly. Non standard PTFE lined end fittings including RJP, Cherry Burrell and TW fittings are also available.
Hose End Fitting Materials
(1) Mild Steel (MS) End Fittings - These are manufactured from any suitable grade of carbon steel and are zinc plated and iridescent (gold) passivated after machining.
Note: Due to the greater popularity and availability of Stainless Steel, end fittings ordered as MS are often supplied part, or completely with SS components at no extra charge.
(2) Stainless Steel (SS) End Fittings - All hose end fitting spigots are supplied made from Grade 316 SS, and all ferrules, swivelling nut and flanges are from Grade 304 SS or Grade 316 SS if Grade 304 is not available. The exception is for 1", 1 1/2" and 2" DIN specification PN10 flanges, which are supplied in 1.4571 (AISI 316Ti) SS. Grade 316 SS and Grade 304 SS, depending upon the method of manufacture, will be one of the following.

Corroflon Hose Lengths
Corroflon hose assemblies are made up to the specific lengths required. The hose length is taken as the length from the sealing face at one end of the hose to the same at the at the other end. The length tolerance is +10% -0% for lengths above 1 metre and +5% -0% for lengths up to 1 metre. Closer length tolerances are possible but will incur an extra charge.

For assemblies with Non Lined end fittings and for PTFE lined end fittings on Rubber Covered Hose, the minimum lengths are longer, +4" (100mm) up to 1 1/2" bore, +6" (150mm) for larger sizes.
