Sizes and part numbers
4 Parker part numbers — the Sizes & Part Numbers tab lists each with its end thread and hose bore. Parker numbers read style and series, then end size, then hose size: 10577-8-8 is a -8 end on -8 (1/2") hose.
Assembly
Crimp the fitting only onto a hose Parker approves for the series, using the crimper and die setting Parker publishes for that fitting and hose. Do not mix fittings and hose from different series or makers in one assembly; the assembly is only rated as a matched combination.
