PJi® FunnelCap-BC Oil Bottle Funnel Cap with Bottle Fittings

The PJi® FunnelCap-BC Oil Bottle Funnel Cap with Bottle Fittings is a spill-proof funnel cap designed to help aviation maintenance professionals fill piston engine oil and service aircraft gearbox systems with less mess and less risk of contamination. Built to create a tight seal at the bottle and route fluid through a flexible hose, this funnel cap supports cleaner servicing practices, helps reduce drips and splashes, and aligns with FOD prevention expectations in aviation maintenance and ground support operations.

In real maintenance conditions, oil servicing often happens in tight spaces where a small spill becomes a bigger cleanup and inspection issue. FunnelCap-BC improves control by positioning the hose directly into the filler opening, reducing the chance of oil contacting engine bays or accessory areas. The leak-proof storage approach also helps when a bottle is partially used: the hose end can be sealed with the red cap to help prevent leakage and reduce exposure to debris. This also connects naturally to common search needs like an oil bottle spout with cap, but optimized for maintenance-grade handling and repeat use.

Key Features

• No-spill design that helps prevent oil spills during piston oil filling and aircraft gearbox servicing.
• Leak-proof storage capability for open, half-used oil bottles to help reduce waste and cleanup.
• Flexible hose routing supports precise delivery into tight filler openings and improves control.
• Space-saving hose clip secures the hose to the container to minimize storage footprint.
• Extendable reach by connecting additional flex hoses when extra distance is required.
• Removable hose option for simplified cleaning, replacement, or alternate configuration.
• Red hose end cap seals the outlet to help prevent leakage and limit contamination exposure.
• Versatile for use in storerooms, on service carts, and on-aircraft maintenance.

How to Use

• Install the FunnelCap-BC on the oil bottle using slight hand pressure until seated securely.
• Insert the end of the flex hose into the oil filler opening.
• Hold the bottle horizontally with the flex hose at the top to allow air to vent.
• Rotate the bottle slowly until the flex hose is at the bottom position to maintain steady oil flow.
• When finished, install the red cap on the hose end to seal the outlet.
• Use a separate FunnelCap for different oil types to help prevent cross-contamination.

Typical Applications and Industries

• Aviation maintenance and MRO: Piston aircraft oil top-off, gearbox servicing, and line maintenance where spill control matters.
• Ground support operations: Cleaner fluid handling in storerooms and maintenance bays.
• Industrial maintenance and fleet service: Controlled oil transfer in equipment rooms, shops, and field service vehicles.

For teams that care about clean servicing, reliable oil handling, and FOD prevention, the FunnelCap-BC provides a repeatable way to transfer oil with fewer spills and less exposure to debris. It is a practical maintenance tool for aviation and a strong fit in any industry that wants a more controlled oil bottle dispensing method.
