https://www.s4r.fr/web/image/product.template/299/image_1920?unique=e19e028

The S4R KF Vacuum Male Thread Adapter provides a compact transition between a standard KF vacuum flange and a compatible female threaded connection.

Manufactured from 304 stainless steel, the adapter combines a KF quick-flange interface with an integrated male PT pipe thread, allowing vacuum and gas-handling components to be connected to threaded laboratory equipment, valves, manifolds and furnace assemblies.

The S4R range is intentionally limited to four commonly useful configurations: KF16 × 1/4", KF25 × 1/4", KF40 × 1/2" and KF50 × 1/2". Additional KF and thread combinations are available on request.
