1/8” Quick release coupling
                            In the realm of 
quick-release couplings, the 
1/8” size stands as a testament to compact efficiency. These miniature marvels cater to applications where space is at a premium, offering 
seamless functionality without compromising on performance. 
Let's delve deeper into the world of 1/8” quick release couplings, exploring their 
applications, features, and 
why they're a go-to choice for various industries.
Applications
1/8” is the smallest available size for quick-release couplings, generally requested when compactness is the main driver in the choice of a product and for applications characterized by low flow rate.
Some common uses for 1/8" quick release couplings include: vacuum gauges, pressure measurement, liquid cooling systems, hydraulic circuit bleeding.
Features
Faster series HNV (compliant to ISO 7241 part “B”) 
and FFH (compliant to ISO 16028) both contain 1/8” size. HNV 
couplings are available in carbon steel and brass, whereas carbon steel is the only option for FFH series; for this size only (which is not covered by the ISO standard 16028) the surface treatment is CrIII instead of Zinc-Nickel.
