KF Full Nipple (Straight Connector)

The KF Full Nipple provides a straight, rigid connection between two ISO-KF vacuum flanges of the same nominal diameter. Its cylindrical design features a KF flange at each end, allowing vacuum components and piping to be connected in a compact, coaxial arrangement.

Manufactured from high-quality stainless steel, the full nipple offers robust construction and reliable performance in vacuum and high-vacuum applications. The straight-through design provides an unobstructed flow path, making it particularly suitable for vacuum pumping lines, chamber extensions, and connections between vacuum components.

Available in stainless steel 1.4301 (AISI 304) and 1.4404 (AISI 316L), providing material options for different vacuum system requirements.

Technical Specifications

Flange Sizes: DN16, DN25, DN40, DN50 KF

Materials: Stainless Steel 1.4301 (AISI 304), Stainless Steel 1.4404 (AISI 316L)

Flange Connection: ISO-KF (QF / NW)

Configuration: Straight full nipple with two KF flange connections of identical nominal diameter

Design: Rigid, cylindrical straight connector

Sealing: Compatible KF centring rings with elastomer O-ring seals

Applications

Suitable for vacuum chambers, vacuum pumps, pumping lines, vacuum manifolds, laboratory vacuum equipment, and industrial vacuum systems requiring straight connections between components.

The full nipple is particularly useful for extending vacuum lines, connecting equipment with matching KF flange sizes, and creating rigid connections within vacuum assemblies.

Installation and Compatibility

Compatible with standard ISO-KF flange connections of the corresponding nominal size. Each connection requires a suitable KF centring ring with O-ring seal and a KF clamp.

Compatible KF Centring Rings & Seals and KF Clamps are available separately.

For connections between different nominal flange diameters, the KF Straight Reducing Nipple and KF Conical Reducing Nipple are also available.

The achievable vacuum pressure and operating temperature depend on the selected sealing components and operating conditions.
