YELLOW BRASS
AVAILABLE THREADS SAE/NPT
PS 45 BAR
PS 120 BAR
Rhighly robust
Made from bar and hot forged
All fittings described here are not included in the field of application of Directive PED (2014/68/UE) as they are
considered as pipe’s components designed and constructed for installation in air conditioning and cooling systems
where refrigerants (non-toxic, non-flammable and non-explosive) of group II are used, among which all refrigerants
classified as A1 in Annexe E of EN 378-1 (2008) standard, as well as refrigerants
R30
R123
R141H
R245 classified
among other safety groups.
The standard includes, among others, the following well-known refrigerants:
R12
R22
R134a
R404A
R404C
R407C
R410A
R502
R507.
The sealing system between the end of the male fitting and a nut of the 31000, 31001, 31002 and 31003 series needs a special flare near the end of the copper pipe. Flaring of copper pipes (which is forbidden by the national regulations of certain European countries) can be avoided using a sealing system between the end of a male fitting and an adapter with socket welding shank as the copper pipe end is braze welded into the shank pocket. The perfect sealing of the device is obtained by inserting a truncated copper washer (31017/3 series).
