Questions about this product
- Will this air coupler work with standard US-style air hose fittings?
- No, this coupler is designed specifically for the European standard and ISO 6150-B profiles. It won't fit standard US industrial or automotive style plugs. Make sure your existing tools and hoses use EU-style connections before buying.
- What is the maximum air pressure this quick-connect fitting can safely handle?
- This brass coupler safely handles standard operating pressures up to 10 bar, which is about 145 PSI. It has a high minimum burst pressure rating of 40 bar for safety. Do not use it in systems that exceed these limits.
- How do I choose the right thread size for my air line setup?
- We offer this coupler in three male thread sizes: 1/4-inch, 3/8-inch, and 1/2-inch. Measure your tool's port or hose fitting to match these parallel BSPP threads. The 1/2-inch size gives you the highest flow rate at around 0.8 Cv.
