Description
Outer centring ring KF, DN 20/25 with NBR seal is a vacuum sealing insert for standard KF (NW) flange joints used throughout laboratory vacuum technology. The outer centring ring aligns the mating flanges and carries an integrated NBR (nitrile rubber) seal that provides the elastomer interface needed for a reliable vacuum-tight connection at DN 20/25. Combined with a matching aluminium or stainless clamping ring, it enables fast assembly and disassembly of vacuum lines on pumps, manifolds, traps and instrument ports without permanent fittings. Supplied as a single unit with a low weight of 0,012 kg, the part is convenient as a spare seal assembly or for expanding modular KF plumbing. This outer centring ring from manufacturer Vacuubrand is specified for DN 20/25 KF hardware and supports routine roughing and medium-vacuum work where NBR is chemically and thermally suitable. It fits research, analytical and quality-control environments that rely on interchangeable vacuum connections together with vacuum pumps and related laboratory appliances.

What is this article?
Outer centring ring KF, DN 20/25 with NBR seal, 1 unit(s) is the article on this page. Luminix Health distributes Vacuubrand for laboratory use. It sits in Other instruments & spare parts, in Lab instruments.
Some instruments do not sit cleanly in one measuring principle, and every instrument eventually needs a spare: a lamp, a fuse, a seal, a knob. The spare has to be the part for that model. A near match is a different part. Calibration of the instrument, once it measures, belongs with EURAMET, BELAC and the BIPM.
