Technical Data Sheet

The Series 31500 includes access fittings and valve cores designed for professional A1 refrigeration systems, enabling fast and secure system charging and evacuation.

Once the procedure is complete, a cap with integrated gasket can be installed to prevent any refrigerant leakage. Alternatively, the system can be sealed with a blind nut (item 31001) and a flared copper gasket with stem (item 31517).
The yellow brass body is available in both solid bar machined and hot-forged versions, depending on size and working pressure requirements. Each fitting is designed to house a valve mechanism compliant with ARI STANDARD 720:1997, which allows refrigerant flow simply by pressing the internal pin once correctly torqued into place.

The Series 31500 is offered with SAE or NPT threads, and available in a full range of pressure ratings to suit any installation:
PS: 45 bar (653 psi)
PS: 60 bar (870 psi)
PS: 120 bar (1740 psi)


All components are CE certified and engineered to ensure consistent reliability even under frequent cycling, high pressures, and demanding environmental conditions.
 

Technical features:

  • Fitting body made of brass EN12164-CW614N or EN12165-CW617N
  • Copper pipe EN12735-1
  • Brass mechanism EN12164-CW614N with Neoprene, OLAB-certified 100% PFAS-FREE HNBR or OLAB-certified 100% PFAS-FREE EPDM gasket (depending on the model)
  • Brass caps EN12164-CW614N with Neoprene gasket
  • Available threads SAE / NPT
  • Designed for professional A1 refrigeration systems

COMPATIBLE A1 REFRIGERANT GASES

HFC, HFO, and HFO/HFC blends: R404A, R407C, R410A, R507, R32, R134a
HFO e miscele HFO/HFC: R1234ze, R448A, R449A, R450A, R452A, R1234yf, R1233zd

Our Neoprene compound gaskets have been designed and produced to be compatible with group A1 refrigerant gases (as defined in ASHRAE standard 34).However, in consideration of the infinite application variables (pressure, temperature and mixing percentages), an application check on the system is always required.

HIGHLY ROBUST
Brass bodies manufactured from solid bar or hot forged, designed to withstand system pressures up to 120 bar (1740 psi) with excellent mechanical reliability.


MADE FROM BAR AND HOT FORGED
Two construction technologies tailored to the application: guaranteed structural strength and dimensional precision.


SAFE
Each fitting features a sealing cap that ensures complete tightness after filling or evacuation, protecting against refrigerant leakage.


FULL RANGE
Available with SAE/NPT threads and in multiple pressure ratings: 45 bar (653 psi) – 60 bar (870 psi) – 120 bar (1740 psi), fully compliant with ARI 720:1997 standard and ready for all professional setups.

STANDARDIZED VALVE CORE MECHANISM
Internal thread compliant with ARI STANDARD 720:1997 with pin-operated actuation.


CERTIFIED PERFORMANCE
Designed according to PED Directive 2014/68/EU, with burst resistance tested up to 135 bar.
