Reliable Fittings & Tubing
High Pressure fittings are specifically designed for demanding high-pressure systems up to 10,000 bar / 150,000 psi. They provide extremely pressure-tight connections and are ideally suited for use in hydraulics, isostatics, waterjet technology, and many other applications.
Thanks to innovative technology and high-quality materials, they guarantee maximum safety and durability under the most extreme conditions. In addition, they are highly versatile and suitable for use in petrochemical industries, mining, test benches, food processing, research institutes, and many other specialized applications. Whether standardized or custom-made solutions – WEH offers a wide range of high-pressure fittings for various industries and requirements.
Suitable Tubes & Hoses for Every Application
In addition to fittings, the seamless cold-drawn stainless steel tubes provide pressure-tight connections for demanding ultra-high-pressure applications. They are available in various sizes and lengths, tailored to working pressure and nominal diameter. Complementing this, high-pressure hoses are also available, designed for seamless integration into existing systems.
Suitable Tubes & Hoses for Every Application
Pressure-Tight Safety
Robust Cone & Thread Fitting for Metal-to-Metal, Reusable Connections – Ideal for Extreme Pressure Applications.
Leak-Free & Flow-Optimized
Thanks to precise sealing contours (58°, 60°, 116°, and 120°) and above-average nominal diameters, pressure loss is minimized – ensuring maximum process reliability.
Quick & Easy to Install
Installation-Friendly Design with Identical Dimensions for Elbows, Tees, and Crosses – Ideal for Modular Systems.
Compatible with Imperial & Metric Systems
Available for all common tube sizes (¼”, ⅜”, 9/16″) – with imperial or metric threads, pre-assembled and supplied with matching tube nipples.
Durable & Media-Resistant
Cold-drawn stainless steel and optional special materials for use with demanding media – robust, corrosion- and wear-resistant.
