Description - Swivel flange fitting, integrally PTFE lined and flared.
Specifications - Flanges to ASA 150 (ASME B16.5 Class 150), DIN PN10 or PN16 and BS10 Table E. Other flange ratings to these specifications are also available and other types of flanges can be supplied.
Materials - Grade 316 SS Spigot, Grade 304 Flange and Ferrule, except 1", 1½" and 2" PN10 Flange are Grade 316. Alternative options include grade 316 SS flanges, polypropylene flanges mounted on SS spigot, zinc or nickel plated mild steel flanges, and other materials to special order.
Maximum Working Pressures - These are defined by the flange specification. For standard PN10 and PN40 the maximum working pressures are 10 Bar and 40 Bar respectively. For ASA 150 the maximum working pressure is 230 psi or 16 Bar. Test pressures are 1.5 times the MWP. (Exceptions: when the hose MWP is less than the fitting MWP).

*These are not the correct flared diameters, but they are the maximum diameter to which the PTFE can be flared out for that flange size. If the full size flare diameter is required, please contact Aflex Hose for a solution.
**Step-Up Flange Fittings on 2" hose.
Because the 2" Bioflex Hose has better flow rates than both 2½" and 3" Convoluted PTFE hoses, it represents a superior alternative when fitted with the larger flanges. It is, however necessary to also "Step Up" the PTFE lined bore, to ensure an diameter match with the mating connector.
This is best achieved using a solid PTFE adaptor plate as shown in the drawing.
Other sizes can also be 'stepped up' if required, for example 1" hose to 2" flange.
