Is the Straight reduction fitting KORO-L, carbon steel compatible with both L (light) and S (heavy) series threads?

Yes. The Straight reduction fitting KORO-L, carbon steel is compatible with both L (light) and S (heavy) series threads. The product description explicitly lists availability as L (light series) and S (heavy series), and its design.24Â° DIN 2353 socket with O-ring incorporating internal and external metric threads.supports use in either series. Material (carbon steel, galvanized) does not affect thread series compatibility.

Can Straight reduction fitting KORO-L, carbon steel be used with metric internal and external threads having different pitch sizes?

Straight reduction fitting KORO-L, carbon steel Format: Yes - Straight reduction fitting KORO-L, carbon steel Format can be used to connect metric internal and external threads with different pitch sizes provided the threads themselves are compatible with the fittingâs sealing system. The KORO-L (24Â° DIN 2353 socket with Oâring) seals on the 24Â° cone and the Oâring; it does not rely on matching thread pitch for sealing. However, mating threads must be mechanically compatible (correct nominal diameter, thread form, and fit) to ensure proper engagement and mechanical strength. If internal and external threads differ in pitch but are the same nominal metric diameter and properly manufactured, the fitting will seal via the cone/Oâring. Always verify thread dimensions, pressure rating, and assembly instructions per DIN 2353 before installation.

Can Straight reduction fitting KORO-L, carbon steel be used with hydraulic systems operating above standard DIN 2353 pressures?

No. Straight reduction fitting KORO-L, carbon steel (light series) is not suitable for hydraulic systems operating above standard DIN 2353 pressures without verifying series rating and application limits. Explanation: The KORO-L description specifies a 24Â° DIN 2353 socket with O-ring, internal and external metric threads, and identifies L as the light series (with S as heavy series). The light series (L) is designed for lower pressure ratings than the heavy series (S). DIN 2353 defines pressure ratings that depend on series (light/heavy), tube size and material; fittings from the light series are intended for applications within the standard DIN 2353 pressure limits for that series only. Using a light-series carbon steel fitting above those limits risks seal failure, thread or body deformation, and catastrophic leakage. Recommendation: For pressures above standard DIN 2353 light-series ratings, use the heavy series (S) or a fitting specifically rated for the higher pressure, verify the exact pressure class for the given size per DIN 2353, confirm compatibility of carbon steel and galvanizing with the hydraulic fluid and environment, and follow manufacturer installation torque and assembly instructions. Conduct pressure testing and, if in doubt, consult the fitting manufacturer or a qualified hydraulic engineer.
