Loc-Line 69540-BLK 3/4" Modular Hose Segments, Bulk 25 ft (54 Segments), Black

Loc-Line 69540 is a bulk pack of 54 hose segments for 3/4" hose, which the catalogue lists as bulk 25 ft. It belongs to the 3/4" Loc-Line modular hose system (Lockwood Products, USA), where the catalogue counts 1 segment as 6 elements (manufacturer-stated). This listing has two variants: 69540 in blue (the base part number) and 69540-BLK in black (the -BLK suffix). The catalogue lists this bulk pack in the same 3/4" hose cell as the pack of 2 segments (61501) and the 5 ft and 50 ft coils.

The hose is a ball and socket assembly with enough friction between the parts for it to stay in position once set (manufacturer-stated). The catalogue gives the 3/4" system a standard line pressure of 20 PSI with a flow rate of 1,140 gal/hr, and up to 50 PSI with element clamps on all joints, fully tightened (manufacturer-stated). It adds that every application has variables that affect the maximum hose pressure and recommends testing whenever possible (manufacturer-stated). The catalogue lists standard acetal parts, which include the blue, black, grey and white colours, with a maximum operating temperature of 170 °F and a melting point of 329 °F (manufacturer-stated).

Common specifications

Key specifications

Pack contents and colour suffixes are taken from the Loc-Line catalogue (2019). 1 segment = 6 elements (manufacturer-stated).

Selecting the right option

This listing offers blue and black. The catalogue prints -BLK (black) and -G (grey) as colour suffixes for this hose, added to the part number when ordering (manufacturer-stated). Match every nozzle, fitting and clamp to the hose system: a 3/4" system part does not fit hose from another system. Use element clamps on all joints if you want to work above the standard line pressure.
