Technical characteristics / specifications

• Line: KF
• Line type: KF
• Product type: Adapters
• Material: AISI 304
• Finish: micro‑bead blasted
• Function: welding flange for vacuum connection + female threaded sleeve as seat for male BSPP counterpart

Applications
Designed for connecting KF vacuum components to pipelines or fittings with Gas G (BSPP) female threads. Typical uses include vacuum chambers, process equipment and industrial vacuum systems where KF flanges must interface with BSPP‑threaded components.

Material and finish
Manufactured in AISI 304 stainless steel. Micro‑bead blasted finish reduces surface roughness while maintaining dimensional tolerances suitable for vacuum applications.

Ordering information
Choose the item code matching required DN and thread size. Verify compatibility of male BSPP counterpart before installation. Contact supplier for custom configurations or quantity pricing.
