DC Sports 2.3" 59mm Crush Ring Gasket

DC Sports 2.3 Inch Crush Ring Exhaust Gasket - 18212-SB2-961A

The DC Sports 2.3 inch crush gasket (SKU: 18212-SB2-961A) is a high quality DC Sports exhaust gasket built to give you a tight, long lasting 2.3 inch exhaust seal. This multi-layer exhaust gasket uses a graphite core with an integrated crush ring, so this graphite exhaust gasket can handle real heat, vibration, and less-than-perfect flanges in both performance and replacement exhaust setups.

Built for a Solid, Repeatable Seal

This DC Sports graphite gasket uses a multi layer graphite stack that lets it conform to small waves and marks on the flange surface. Graphite lives happily in high temperature, high cycling environments without turning brittle or crumbling, which makes it a smart choice for a universal graphite gasket. As you torque the joint, the layers compress to close up micro leaks and help keep backpressure where it should be.

At the core is the integrated crush ring gasket. That ring concentrates clamp load right at the inner edge where exhaust gas actually moves, turning this into a very effective exhaust crush ring gasket. When you tighten the hardware, the ring deforms and fills gaps that flat, one-layer gaskets usually leave behind. The combo of multi-layer graphite and crush ring design helps cut exhaust noise, fight leaks, and keep performance consistent over time. We run this same DC Sports gasket seal on our own test cars.

Fitment and Sizing

• Outer Diameter (OD): 59 mm (2.3 inch)
• Inner Diameter (ID): 2.0 inch
• Type: Universal crush ring exhaust gasket

Sized as a 59mm crush ring gasket and 59mm exhaust gasket, this part fits exhaust flanges that match the listed inner and outer diameters. You’ll usually see it used between a mid pipe and muffler, or at joints in a cat back system where you want a reliable DC Sports graphite gasket instead of a cheap paper spacer. Measure your tubing and flange ID/OD before you order so this 2.3 inch crush gasket actually matches your setup.

Universal Application

This gasket is a true universal crush gasket — it’s not locked to a specific chassis or part number. It works as a universal exhaust gasket anywhere the flange dimensions line up. Thanks to the multi layer graphite, it doubles as a universal multi-layer gasket for a lot of street and performance layouts: custom cat backs, axle backs, and mid pipe joints. Whether you’re swapping components or just replacing a tired seal, this universal graphite gasket is an easy drop-in for 2.3 inch flange connections.

Why Multi-Layer Graphite + Crush Ring Works

• Multi-layer graphite construction lets the gasket flex into uneven or slightly warped flanges better than rigid, single layer pieces.
• Strong resistance to exhaust heat and thermal cycling means it holds up as a long term multi-layer exhaust gasket instead of burning out in a few heat cycles.
• The integrated crush ring focuses clamping force where exhaust flows, giving you a more secure 2.3 inch exhaust seal.
• Significantly better leak control than low-grade paper or thin composite gaskets, especially at stressed joints, flex sections, and slip-fit transitions.

Installation Notes

• Clean both flanges fully,  remove old gasket material, rust, and carbon.
• Check for deep grooves, warping, or cracks that might keep the gasket from sealing.
• Tighten flange bolts in a crisscross pattern so the crush ring compresses evenly and the DC Sports gasket seal can do its job.
• Treat it like any other exhaust crush ring gasket: once it’s crushed and you break the joint, plan to replace it.

Key Benefits

• Consistent sealing in high temperature, high vibration exhaust locations.
• Graphite material conforms to minor surface flaws better than rigid metal gaskets or thin composite shims.
• Crush ring design improves sealing when torqued correctly, making this a solid choice for performance exhaust upgrades and repairs.
• Works as a flexible universal multi-layer gasket for many 2.3 inch and 59mm exhaust joints where a universal exhaust gasket is needed.

If you’re assembling or servicing an exhaust with a 2.3 inch flange and you want a dependable 59mm exhaust gasket, the DC Sports 2.3 Inch crush ring gasket (SKU: 18212-SB2-961A) is a proven, graphite based, leak-resistant choice. It’s the same style of DC Sports graphite gasket we trust on our own cars.
