Explanation hose brands
There are different brands of hoses available. Due to the high pressures, these must fit perfectly on the hose couplings. The Frigoclic couplings have been developed for Artic NK (Refrimaster) and Frigostar slangen.
Explanation hose coupling type
The sealing of hose couplings on the screw side can be divided into three categories:
Explanation hose coupling size
The size of the hose connector on the screw side can be measured at the component where the hose connector is screwed on (a) or at the hose connector side (b). The sizes are finally expressed in English sizes:
| Size | Pitch | A | B |
| 9/16 | 18UNF | 14,4 | 12,9 |
| 5/8 | 18UNF | 15,9 | 14,5 |
| 11/16 | 16UN | 17,5 | 15,9 |
| 3/4 | 16UNF | 19,1 | 17,5 |
| 3/4 | 18UNS | 19,1 | 17,7 |
| 13/16 | 16UN | 20,6 | 19 |
| 7/8 | 14UNF | 22,2 | 20,4 |
| 7/8 | 18UNS | 22,2 | 20,8 |

Explanation hose size
The coupling depends on the inner size of the hose. Frigoclic has a fixed size for this and these can be used on Artktik NK (Refri-Master) and Frigomaster. These hoses do have a different outer size, so different hose clamps are needed for this. The inner hose size will also always be on the hose in several places (hopefully it can still be read)..
| G-size | English size | Inner size | Outer size Arktik NK |
| G6 | 5/16 | 8mm | 12,7mm |
| G8 | 13/32 | 10,5mm | 16mm |
| G10 | 1/2 | 13mm | 18,1mm |
| G12 | 5/8 | 16mm | 21,7mm |
