16mm Carburettor & Exhaust Dust Cap Set - O.S. Engine OS73301612  [OS73301612]

Protective 16mm dust caps for model engines

This RC-scale accessory is a simple three-piece dust cap set designed to seal 16mm carburettor and exhaust openings on model engines. The caps match 16mm interfaces and are supplied for workshop servicing, maintenance and short-term storage to keep dirt and debris out of internal passages.

Fitting is straightforward: press each cap into the carburettor throat or exhaust outlet until it sits with a light interference fit. They are protective covers only and must be removed before operating the engine; they do not serve as tuning parts or performance components.

Use the set when transporting models, during bench tuning sessions, or while performing engine servicing to prevent contamination inside the carburettor barrel and exhaust runner. The three-piece count makes it easy to cover several openings or keep an extra cap on hand.
