πΊπΈ PROUDLY MADE IN THE USA | AR-EXHAUST
Upgrade your exhaust connection with this quality, USA-made 3/4" NPT Male Exhaust Flange Adapter, designed for select small Briggs & Stratton and Tecumseh engines.

Includes premium 304 stainless steel mounting hardware and an exhaust gasket.
EXHAUST MOUNTING HOLE SPACING: 1.50" CENTER TO CENTER
PLEASE SEE PHOTO #2 FOR EXACT FLANGE MEASUREMENTS.
This adapter is designed to fit certain small Briggs & Stratton and Tecumseh engines, but it is NOT compatible with every model or engine version.
Designed to mount directly to the engine's exhaust port, providing a standard 3/4" NPT male threaded connection for compatible exhaust components.
May also mount directly to certain mufflers that feature a matching two-bolt mounting pattern. Compatibility with individual mufflers is not guaranteed.
IMPORTANT: Engine brand, model, and horsepower alone do not guarantee compatibility. Always verify actual measurements.
Please note: 3/4" NPT does NOT mean the thread measures 3/4" in outside diameter.
NPT (National Pipe Taper) threads use nominal pipe sizes, which differ from their actual outside diameters.
A standard 3/4" NPT male thread has an outside diameter of approximately 1.05", not 0.75".
Please review the NPT thread size charts included in our product photos to understand nominal pipe thread sizing and select the correct connection.
We manufacture our exhaust components with careful attention to material selection, welding quality, and durability.
Construction Details:
The stainless steel threaded connection is TIG welded directly to the mild steel flange.
Material Clarification: The mounting flange is mild steel, not stainless steel. The threaded connection and included mounting hardware are 304 stainless steel.
The mild steel flange is supplied uncoated and may develop surface rust when exposed to moisture or high temperatures.
Designed for select small-engine exhaust applications, including certain:
Known Incompatibility:
Not compatible with the Tecumseh HS50 5 HP engine.
Compatibility is determined by the actual mounting dimensions, flange shape, exhaust opening, and available clearance, not simply by engine manufacturer or horsepower.
Hardware Note: The included mounting bolts are suitable for certain engine applications. Different bolts or additional hardware may be required depending on your engine.
This product is an exhaust flange adapter, NOT a muffler or silencer.
It contains no internal baffles or sound-reducing components.
If operated without a muffler or suitable exhaust system, the engine will produce significant exhaust noise.
Use appropriate exhaust components and maintain safe clearance from heat-sensitive parts.
