Hand PumpHand pump suitable for use with all of our Hand Pump cylinders

the Daft Punk harness kit includes a machined aluminium hand pump cylinder (40mm or 50mm internal diameter)

50mm): The size refers to the internal diameter of the SPT

and the polished aluminium base ring

The SeriousKit Milker’s lube supply can be connected to the cylinders for ‘wet’ milking (lube supply hose included)

Bi Polar SPTs and the O-Ring constrictor SPT to the Original Surge Milker

The bag is fitted with a machined aluminium harness mount with the same internal diameter at the vacuum cylinder

Designed to be used with the Milker’s constant lube feed

The tool makes removal of constrictions easy and helps with general SPT maintenance

Other connection options could be cage to sound and cage to aluminium base

The length of the lower cylinder can also be chosen as this governs how much of the penis is in the upper chamber – and so in contact with the e-stim liquid

23mm liner - used on our 30mm internal diameter SPT (External diameter 40mm)

40mm or 45mm constriction for 50mm SPTs
