Universal Carburettor Nipple No.15

This universal nipple No.15 from O.S. Engine is an RC-scale carburettor fuel connector intended as a straightforward replacement part for worn or damaged fuel nipples on glow engine setups. It serves as the interface between the carburettor outlet and flexible fuel tubing, enabling reliable fuel flow on model engines used for hobby and track maintenance.

Installation is typically simple: remove the old nipple, inspect the carburettor outlet for debris, and seat the replacement nipple according to the carburettor's attachment method. Depending on the carburettor design the nipple may be a press fit, require a retaining clip, or be secured with a small clamp, so verify the carburettor manufacturer’s guidance before final assembly.

In tuning and servicing workflows the part plays a small but important role — a clean, properly seated nipple preserves consistent fuel delivery and reduces leaks that can affect idle and throttle response. Use appropriate fuel tubing, check for tight seals, and inspect regularly as part of routine engine maintenance.
