Rhino Spinjet Mechanism Piston

Mechanism Piston for Rhino Coffee Gear Pitcher Rinsers.

Dimensions: 35mm (L) x 4mm (Head:11mm in diameter)

Suits: Rhino Spinset variations ONLY - RHSPINSET, RHPR600-S, RHPR300-S

The Part That's Hard to Source — In Stock Here
The mechanism piston is the internal component inside the Spinjet valve that translates the downward press of the actuator plate into the spray-and-spin action of the valve head. When it wears, deforms, or fails, the Spinjet stops actuating correctly — but because it's a small internal part rather than a complete valve assembly, it's not always easy to find as a standalone replacement. As one Coffee Addicts customer from Surrey, BC put it simply: "Rhino Rinser Piston you can never find." This page stocks it. The piston is 35mm in length with a 4mm shaft and an 11mm diameter head, and is the genuine Rhino replacement part for the Spinjet mechanism.

Compatibility — Spinset Variations Only
This mechanism piston suits the following Rhino Spinjet rinsers: RHSPINSET (Spinjet Spray Assembly), RHPR600-S (Spinjet Pitcher Rinser 600mm), and RHPR300-S (Spinjet Pitcher Rinser 300mm). It is compatible with Spinset variations only — not suitable for the RHPR150-S (Compact Spinjet Pitcher Rinser) or the RHPR600 (standard non-Spinjet Pitcher Rinser 600mm). Confirm your model number before ordering. The piston is also one of the components covered by the Rhino Spinjet Valve Service Gasket Kit (RHSPVSK-01), which includes the spring, piston gasket, and three O-rings for routine maintenance servicing — if the piston itself is intact but the seals are worn, the gasket kit may be the appropriate service part rather than this piston.
