Superior Static Seal for High-Stress Systems
Our End Face Sealing Flange is a critical connection component for hydraulic systems. It is designed to provide a perfect static seal under high pressure and strong vibration, preventing leaks entirely. The flange features a precision-machined sealing surface and a carefully engineered bolt load design, ensuring the seal remains intact even during pressure spikes. This helps your system operate continuously with minimal downtime and reduced maintenance risks. Our product is a reliable choice for demanding applications.
Built for Tough Hydraulic Applications
The product is widely used in hydraulic systems for excavators, cranes, and concrete pump trucks. Its primary role is to create secure connections between essential components such as valve blocks, cylinders, pumps, and motors. It withstands peak system pressures and maintains a solid seal in mining machines that operate under heavy loads all day or construction machines with constant start-stop vibrations. This flange serves as a foundation for a safe and efficient hydraulic circuit. Choosing our End Face Sealing Flange means choosing long-term reliability.
Strong Materials and Clear Specifications
We manufacture this flange from durable materials such as forged alloy steel (42CrMo), stainless steel 316, and high-strength ductile iron, providing excellent strength and corrosion resistance. The sealing surface undergoes treatments like induction hardening or hard chrome plating to enhance wear resistance and longevity. Our products comply with international standards, including ISO 6162 and SAE J518, ensuring compatibility with components from other brands.
Flexible Options and Custom Fit
Our End Face Sealing Flange is available in both metric and inch sizes, with standard pressure ratings from 250 Bar to 600 Bar. Recognizing that one size does not fit all designs, we offer custom solutions, including modifications to flange shape, bolt hole patterns, and seal groove types. This helps save space, reduces the number of parts, and simplifies assembly. With Taizhou Liuhuan Machinery Co., Ltd, you gain more than a connector-you gain a partner committed to optimizing your entire system.
