New Matched Pair MDC 20625 Stainless Steel 6-Inch V-Band Flange Clamps
This listing is for (1) one matched pair of premium MDC 20625 stainless steel 6-inch V-band clamps. Engineered specifically for demanding high-performance automotive exhaust systems, industrial turbo manifolds, commercial diesel piping, and high-vacuum lines, these clamps utilize internal segmented V-retainer brackets. When the heavy-duty adjustable T-bolt fastener assembly is torqued down, uniform radial force wedges flanged pipe lips tightly together to form a highly resilient gas-tight seal without needing traditional multi-bolt flat gaskets. Constructed out of premium-grade corrosion-resistant stainless steel, these components are optimized to resist extreme heat cycling, stress oxidation, and harsh operating conditions.

Compatibility & Application Advisory
- Application Use: Industrial turbocharger downpipes, commercial diesel exhaust emission lines, custom performance exhaust manifolds, and heavy vacuum chamber plumbing lines.
- Mating Flange Clearance: These clamps are specifically intended for a flanged 6-inch pipe collar configuration. The buyer is responsible for verifying that the inner V-groove width perfectly matches the combined thickness of the mating pipe flanges before final torque application.
- Purchasing Perspective: For the fleet mechanic, shop owner, or maintenance engineer, this New Old Stock pair gives you drop-in OEM-spec components without standard distribution inflation or back-order delays. Keeping this high-integrity pair on your parts rack protects your operations from emergency downtime when field lines fail.
- Value-Add Advantage: Built with robust multi-point deep spot welds holding the heavy-gauge inner V-segments, these clamps deliver exceptional mechanical joint stability and prevent localized exhaust leaks under high-vibration conditions.
