Valve Sleeve Buna AP-6739 Good Price Waterjet Parts

The Valve Sleeve Buna AP-6739 is a high-quality elastomer sealing component designed for use in low-pressure valves, pump assemblies, and hydraulic circuits of WaterJet Cutting Machines and industrial fluid systems. Its main function is to provide a tight, leak-proof seal around the valve stem or plunger, ensuring smooth fluid control, stable operation, and long-term resistance to wear and pressure cycling.

Constructed from premium Buna-N (Nitrile Rubber) material, the AP-6739 valve sleeve offers excellent oil resistance, water compatibility, and elastic recovery. The Buna compound provides a balanced combination of chemical durability, temperature resistance (typically from -30°C to +120°C), and compression set stability, making it ideal for both hydraulic oil and water-based systems. Its precision-molded structure ensures perfect alignment and sealing performance within the valve assembly, minimizing leakage and extending component lifespan.

The Valve Sleeve Buna AP-6739 is fully compatible with KUNDA, KMT, FLOW, and OMAX waterjet systems, and is commonly installed in inlet valves, check valves, and actuator assemblies. It serves as an OEM-equivalent or replacement part for systems requiring reliable sealing performance under varying pressure and temperature conditions.

Used across multiple industries — including metal cutting, stone processing, ceramic fabrication, and composite material production — the AP-6739 valve sleeve ensures consistent operation, low maintenance, and dependable system protection.
