Common specifications

Key specifications

Pack contents and colour suffixes are taken from the Loc-Line catalogue (2019).

Selecting the right option

The catalogue lists a reducer and a Y reducer for 1/2" to 1/4"; this listing is the reducer. It is not the 1/2" to 1/4" female pipe reducer (50659, 51759), which sits in the catalogue Tefen couplings section. Pack quantities in this listing: pack of 2: 51821; pack of 20: 59869 and 59869-BLK. The catalogue prints -BLK (black) and -G (grey) against the bulk number 59869 (manufacturer-stated); this listing includes the black version. Match the part to the hose system: a 1/2" system part does not fit hose from another system.
