MKC20-8-P is a gear-reducer-specific OIL SIGNAL indicator with a protective BC gunmetal cover. It is intended for local observation of oil flow at a gearbox and has an 8 mm tube connection. Its polycarbonate tube and SUJ steel ball distinguish it from the standard acrylic-tube MKC catalog models.

Gearbox-specific visual checking
This model is identified separately for gear-reducer installation. The transparent tube and internal ball provide a local indication of oil movement. Use the complete -P designation when identifying a replacement. Match the gearbox connection and mounting arrangement to the dedicated product drawing, and confirm suitability with the actual reducer design. The standard product information does not assign a calibrated L/min range to this model, so flow-observation capability should not be converted into a numerical measurement claim.
Installation and operating checks
Confirm the installation orientation, flow path and connection arrangement for the selected model before assembly. Keep the viewing area accessible so the oil movement can be inspected during operation. Check the specified temperature and pressure limits against the actual oil circuit and verify material compatibility with the oil. Inspect the transparent tube, fittings and any seals for leakage or damage, and confirm visible oil movement after commissioning. A visual indicator supplies local information; any required automatic shutdown or remote alarm must be specified as part of the system design.
The cap nuts and sleeve are listed as Cu, the spring as SUS304 and the ball as SUJ steel. These materials are intentionally retained separately from the nylon-ball and acrylic-tube specifications of the general-purpose families. Confirm the gearbox mounting details and oil conditions when replacing an existing indicator.

Information to provide when ordering
Specify the complete model or configured series, oil type or viscosity, normal delivery conditions, inlet and outlet connections, and available mounting space. For copper-tube models, state the tube outside diameter. For threaded models, distinguish R male from Rc female connections.
