Plastic Refrigerant Filling Valves

Plastic Refrigerant Filling Valves

Schrader Pacific Advanced Valves is breaking new ground with its range of Plastic Refrigerant Filling Valves for plastic-made air conditioning lines, saving weight on air conditioning circuits.

Valves are suitable for both R-1234yf and R-134a refrigerant application as well as for both low and high pressure sides of the refrigerant circuits.

For our range of Plastic Refrigerant Filling Valves, several line connection designs and welding geometries are possible and can be adapted to your own requirements.

Schrader Pacific Advanced Valves Integrated Core – Why a new core technology designed for plastic application?

Turning the line and the filling port to plastic, new concerns are to be considered. 

Indeed, plastic properties are less stable under mechanical & thermal solicitation than those of aluminium. 

Schrader Pacific Advanced Valves Integrated Core –Key Advantages :

  • Designed for Manufacturability. Not screwed but inserted valve core (Better Cleanliness)
  • Enhanced Product Performances. No risk with plastic creep issues (Excellent Permeability Properties)
  • Secured Product Life. Non-removable core (Prevents consequences from poor disassembly / reassembly)

Since plastic welding process is generating very low level of heat as compared to aluminium brazing process, the Schrader Pacific Advanced Valves Plastic Refrigerant Filling Valves can be delivered already assembled.

In order to guarantee high quality, all of the assembled valves (stem + core inside) are 100% inspected by camera and 100% controlled for sealing.

Refrigerant Filling Valves

Refrigerant Filling Valves

Schrader Pacific Advanced Valves offers a complete range of air conditioning Refrigerant Filling Valves for the following gases: R134a, R1234yf or R744, as well as for both low and high pressure sides of the refrigerant circuits.

Composition of a Schrader Pacific Advanced Valves air conditioning valve :

Since Refrigerant Filling Valves are usually welded to aluminium air conditioning systems, Schrader Pacific Advanced Valves delivers the following components separately:

The high- and low-pressure valve stems made of aluminium ; the valve core and the sealing cap.

Schrader Pacific Advanced Valves Refrigerant Filling Valves are designed to have maximum flow and therefore as short as possible filling rate.

All elastomers of Schrader Pacific Advanced Valves are tested in the laboratory for compatibility with air conditioning gas and compressor oils.

The valve stems fully comply with the SAE J639 standard, and Schrader Pacific Advanced Valves offers all types of attachments used for welding on aluminium systems. The filling valves can thus be divided into different categories depending on the form of their stem; saddle ; pin; bore.

In order to guarantee high quality, all of the valve stems are 100% inspected by camera and all of the cores are 100% controlled for sealing.

A Schrader Pacific Advanced Valves valve core combined with a Schrader Pacific Advanced Valves valve stem guarantees the best results in terms of permeability, a decisive criterion for the efficiency of air conditioning systems.


Beyond Refrigerant Filling Valves, Schrader Pacific Advanced Valves can also support your need with a complete range of Thermal Management Valves, particularily on the refrigerant circuit for which you can find Electronic Expansion Valve as well as Pressure Relief Valves and Check Valves.
