KDM10 KDM20 Multi-Tube Pneumatic Connectors, 4-8 mm

KDM Series Multi-Tube Pneumatic Connectors

Connect and disconnect 10 or 20 pneumatic tubes together. The rectangular plug-and-socket assembly is designed for removable panels, machine sections and component replacement. Choose a complete set, a male plug only or a female socket only; the selected option determines what is supplied.

Compact connection, convenient maintenance

• Multi-tube docking: connect or separate multiple lines together, reducing installation time and the risk of mixing up lines.
• Space-saving layout: takes less mounting space than multiple separate panel-mount straight connectors.
• Push-in tube connections: quick tube installation and removal.
• Secure assembly: fastening screws hold the plug and socket halves together.
• Resin construction: smooth, burr-free surfaces with hardness, pressure resistance and wear resistance described in the supplied product information.
• Model coverage: 10- and 20-connection assemblies, with 4, 6 and 8 mm tube OD options offered on this page.
• Sealed connections: sealing rings support pneumatic connection; observe the leakage limitation below.
• Easy installation: standard panel-mount brackets allow installation from the panel front.

Construction and component guide

The assembly uses standardized components and selected materials. The core parts are the push-in plug fittings, socket fittings, plug cover, socket cover, fastening screws, panel-mount brackets and bracket screws. The catalog also identifies the retaining plate, E-type retaining rings and sealing rings. Locating features align the mating halves at the correct position.

Operating specifications

Important: leakage is not zero. The catalog states that these connectors must not be used for vacuum holding or leakage tests. A sealed connection is not a zero-leak guarantee. The source overview gives a positive-pressure range, while the series catalog also describes vacuum service; confirm suitability for the actual application.

Model selection and reference weights

Select only the models shown in the purchase selector. The 3.2 mm / -23 entries below are retained as series-reference information, not additional purchasable variants. Weights are catalog reference values for the listed assemblies, not shipping weights.

Separate plug and socket assemblies

Single plug and socket assemblies are sold separately and are not complete sets. Release collars are blue.

Individual fitting references and mixed tube sizes

The catalog describes replaceable plug and socket fittings at individual positions, allowing a mixture of tube sizes within an assembly. This is technical reference information; individual replacement fittings and mixed-size assemblies are not added as purchase options on this page.

1. Use a cross-head screwdriver to loosen the small cross-recessed pan-head screws and remove the retaining plate from the cover.
2. Replace the fittings in the required positions, then refit the plate to the cover and tighten its screws.

Main component materials

The supplied series reference describes a copper-ion-free specification with electroless nickel plating. Confirm the required material and finish for the selected configuration.

How to connect and disconnect

1. Disconnect: loosen the fastening screws to separate the plug side from the socket side.
2. Connect: align the mating locating features and fit the plug cover to the socket assembly. Tighten the fastening screws by hand, then secure them with a No. 4 (4 mm) hex key.

Panel mounting and removal

The standard brackets allow installation from the front of the panel without separate mounting-screw holes. Prepare the rectangular panel cutout shown below. The descriptive text specifies a panel thinner than 5 mm, while the drawing marks 5 mm maximum; check the actual panel and assembly.

1. Use a cross-head screwdriver (JIS No. 2) to loosen the four bracket screws on the socket side until the brackets contact the retaining rings above them.
2. Slide the brackets inward along the elongated holes, then insert the connector into the panel opening.
3. Move the bracket screws outward and tighten them with the screwdriver to secure the socket cover.
4. For removal, loosen the bracket screws until the brackets contact the retaining rings, slide the brackets inward and remove the connector from the panel.

Dimensions and panel cutouts

All dimensions are in millimeters. Drawings below are original source views displayed without redrawing the product geometry. Parenthesized heights apply to the -08 (8 mm tube OD) versions.

Confirm the exact model, mating component, tube outside diameter, panel cutout and operating conditions before installation. Accessories, tubes and other configurations shown in the reference illustrations are not included unless specified by the selected option.
