Flange Specifications
- ANSI B16.5 (also ASME B16.5) Class 150# and 300#
- *DIN PN10/PN16 and PN40
- JIS 10K
- Other Pressure Ratings and Flange Specifications are
also available.
*DIN PN10, PN16 and PN40 Flanges all have the same
dimensions, and so are fully interchangeable.
Pressure Ratings For Flanges
- ANSI 150# = 230 psi (16 Bar), ANSI 300# = 460 psi (32 Bar)
- DN PN10 = 145 psi (10 Bar), DN PN16 = 230 psi (16 Bar)
End Fitting Materials
- Flanges in Grade 304 SS
- Flange Retainers in Grade 316L SS
- Ferrules, most in Grade 304 SS, some sizes in Grade 316L SS
Alternative options for Flange component only:
- Zinc Plated Carbon Steel
- Blue Epoxy Coated Carbon Steel.
90° Elbow Flange Fittings
90° Elbow Integral PTFE lined Flange Fittings are available for
sizes 1", 1 1/2" and 2" - Consult Aflex Hose for details

*Fitting Lengths listed are for RC Grade Hose end fittings. SS and PB Grades end fittings are shorter in length.
**The listed Flare Diameters are not all full size, due to limitations on PTFE flare diameters.
'STEP-UP' PTFE LINED FLANGE FITTING DESIGN FOR CORROLINE HOSE
Because Corroline Hose has better flow rates than
some larger bore sizes of Convoluted PTFE hose, it
represents a superior alternative when fitted with the
larger size flanges in some applications.
It is, however, necessary to also 'Step-Up' the PTFE lined
bore, to ensure a diameter match with the mating
connector.
This is best achieved using a solid PTFE Adaptor Plate,
as shown in the drawing.
Example: a 2" hose to 3" ANSI 150# PTFE Lined Flange Joint.
