High-quality sealing ring 06M121437E for Audi

When it comes to Audi’s high-output engines, cooling system integrity is non-negotiable. The Boigevis Sealing Ring 06M121437E (cross-referenced to 06M121437A) is precision-engineered for critical coolant junctions—specifically designed for water pump flanges, thermostat housings, and crossover pipes in Audi 2.9 TFSI, 3.0 TFSI, and 4.0 TFSI V6/V8 engines found in S4, S5, S6, RS5, and Q7/SQ7 models.
Manufactured from high-grade FKM (Viton®-equivalent) rubber, this sealing ring resists permanent deformation under extreme thermal cycling (up to 200°C) and aggressive G13/G12++ coolant additives. Unlike generic seals that harden and leak, Boigevis units undergo rigorous compression-set and Shore A hardness testing to maintain elasticity and ensure a lifetime of leak-free performance.
Available in Boigevis retail packaging, neutral bulk cartons, or custom private-label kits complete with torque specifications. Consolidate your sourcing with our full Audi sealing portfolio—water pumps, thermostats, oil cooler gaskets, and sensor O-rings—all shipped under one invoice with export-grade packing.
Perfect for performance shops, importers, and Audi specialists demanding OEM-level reliability. Send your VIN, engine code, or target market for real-time stock checks, tiered pricing, and a ready-to-ship quotation.
