O.S. Engine OS73301612 Dust Cap Set for 16mm Carburettor and Exhaust (3 pcs)  [OS73301612]

16mm dust caps for RC engines

This RC-scale accessory is a straightforward dust cap set intended to cover 16mm carburettor and exhaust openings on model engines. The kit contains 3 pcs sized to match 16mm interfaces, supplied for general workshop use, maintenance and short-term storage to keep debris and dust away from internal passages.

Installation is simple: press each cap into the carburettor mouth or exhaust port until it seats with a light interference fit. Caps are intended as protective covers only and should be removed before running the engine; they are not an operational component for tuning or performance adjustment.

Use this set when transporting models, during bench tuning sessions, or when performing engine servicing to prevent contamination inside the carburettor barrel and exhaust runner. The three-piece count makes it convenient to cover multiple openings or keep a spare on hand.
