A one-piece forged body is significantly stronger than an elbow made by welding two pieces together. The continuous grain structure of a forging provides superior resistance to the high-pressure pulses (hydraulic shock) and constant vibration that can cause welds to fail over time.
The "L" (Light) and "S" (Heavy) series correspond to different pressure ratings as defined by the DIN 2353 standard. The S serieshas a more robust, heavy-wall construction for higher pressuresystems (up to 630 bar), while the L seriesis more compact and designed for medium-pressure applications (up to 315 bar).
Yes, any bend in a system will create some pressure drop. However, our elbows are designed with a smooth, full-flow internal bore to minimize turbulence and keep pressure loss to a minimum, ensuring your system operates efficiently.
Our fittings are manufactured to be dimensionally compliant with the DIN 2353 / ISO 8434-1standard, making them interchangeable with other brands that also adhere to this standard, such as the Parker Ermeto (EO/EO-2) series. While Swagelok also offers some DIN-compliant products, their primary offering is double ferrule, so careful verification is needed. For critical applications, we always recommend using a consistent set of Stark components.
