## Questions & Answers

**Q: Can it be adapted for water please**
A: I would say without doubt doubt yes. If it can handle 100psi from a compressor, then it would easily handle mains water pressure.

**Q: Do thes work with bostitch air line fittings**
A: yes

**Q: What is the significance of type 'd' in the description. i have seen different size euro male fittings (i.e. not pcl)**
A: Industrial grade

**Q: Will these fit onto a standard threaded air valve, such as a tyre valve ??**
A: No these are bigger fittings than tyre valves. They connect on hoses similar size to garden hose pipes. And connect to compressed air tools. I hope this helps you. Cheers

## Customer Reviews

### ⭐⭐⭐⭐⭐ No more leaks
*by A***R on 24 April 2023*

Good quality product a great price and now I have no more air leaking from the joints

### ⭐⭐⭐⭐⭐ Air couplings
*by R***N on 23 September 2025*

Again this little set of air components (couplings) does what it says on the tin. Easy to use.

### ⭐⭐⭐⭐ Seem fine, slightly smaller aperture than some
*by M***Y on 11 March 2021*

Good price and seem fine. Hole is perhaps a bit small compared to some I have used. Note there are only 4 with female threads, it does say this in description. I enlarged hole a fraction for the one fitted on paint gun because that needs flow more than pressure. Overall happy.
