Polyvinylidene fluoride (PVDF) DN 5 coupling plug with 4×6 mm union nut. A pneumatic coupling is used to quickly connect air tools to a compressed air line.
The coupling has a non-return valve to prevent backflow and the push-in socket also closes when disconnected. This is considered a double-sided shut-off design. The operating pressure range is 0 to 8 bar (0 to 116 psi). The coupling is suitable for temperatures between -20 to 120 °C (-4 to 248 °F).
Pros:
- DN 5 plastic couplings are compatible with the metal quick couplings DN 5
- These are often considered a good alternative to brass couplings
- They are a cost-efficient alternative to stainless steel versions
- The plug has a double sided shut-off design, which keeps the line pressurized and prevents backflow
