AP Exhaust 8820 Flex Coupling 300 Series Stainless Steel 2.25" Core No Necks 8" OAL

The AP Exhaust 8820 is a stainless steel exhaust flex coupling engineered to absorb vibration, reduce exhaust leaks, and accommodate thermal expansion in automotive exhaust systems. Built from 300 Series stainless steel, this flex coupling delivers lasting corrosion resistance and durability under the high heat and stress of everyday exhaust operation.

Key Features:

• 2.25" (2-1/4") inner core diameter — compatible with standard 2.25" exhaust tubing
• 8" Overall Length (OAL) — full flex length with no neck extensions
• No-neck design — direct slip-fit installation into existing exhaust piping
• 300 Series stainless steel construction — resists rust, corrosion, and high-temperature degradation
• 2-ply convoluted bellows inner core — maximizes flexibility while maintaining exhaust flow
• Designed to reduce vibration transfer and prevent stress cracking in exhaust pipes
• Available as a universal fit component for use in custom or replacement exhaust work

AP Exhaust Technologies has been manufacturing exhaust components since 1927, producing mufflers, exhaust pipes, flex couplings, and catalytic converters to meet the needs of automotive service professionals. The 8820 flex coupling is part of their comprehensive line of stainless steel expansion joints offered in a range of diameters, lengths, and attachment styles.
