Pioneer HR1505 Adapter for Strong Arm Tarping Systems Item #: 20076 Part #: HR1505 Adapter, -8 SAE M x -6 JIC M
The HR1505 is an adapter needed to put the L adapter onto the motor itself. If you try to put the L fitting directly on the motor, it would be too close to attach the hose fitting. The hose end is too large without the HR1505 adapter on there.
