Main port size, branch port size, wall thickness, branch angle, silicone compound, Shore A hardness, color, tolerance and packaging can be customized according to confirmed specifications or samples.
Silicone Y-Connector, also known as Silikon-Y-Hahn, is a flexible molded silicone connector used to join or split compatible tubing paths in a Y-shaped configuration. It supports three-way connection, tube routing, flow distribution and compact assembly in equipment systems. Port size, branch angle, wall thickness, hardness, color and packaging are available upon request.
Silicone Y-Connector — Three-Way Branch Fitting for Fluid and Tubing Systems
The Silicone Y-Connector, referred to in German as Silikon-Y-Hahn, is a molded silicone rubber three-way branch fitting designed to split or combine flow paths between one main line and two secondary lines, or the reverse. Molded from 60 Shore black silicone in RAL 9005, this connector features a Ø30mm main body diameter with multiple stepped bore diameters at each branch outlet, making it suitable for fluid handling, tubing routing, and general laboratory or process applications requiring a flexible Y-shaped junction.

What Is a Silicone Y-Connector?
A silicone Y-connector is a flexible, one-piece molded fitting shaped like the letter Y, used to join or divide two flow paths into a single line, or split one line into two, within a tubing or fluid handling system. This reference design measures 95mm in overall length with a main body diameter of Ø30mm, branching into secondary bores stepped at Ø16mm, Ø13mm, and Ø9mm, with outer branch diameters of Ø17mm and Ø17.6mm to accommodate different tubing sizes at each leg. The bores are specified as burr-free, ensuring smooth internal surfaces that support unobstructed flow and reduce the risk of particulate contamination or turbulence at the junction point.
Dimensional Profile
| Feature | Reference Value |
|---|---|
| Overall length | 95 mm |
| Branch section length | 32 mm |
| Secondary length reference | 24.5 mm |
| Main body outer diameter | Ø30 mm |
| Branch bore diameter (large) | Ø16 mm |
| Branch bore diameter (medium) | Ø13 mm |
| Branch bore diameter (small) | Ø9 mm |
| Outer branch diameter (1) | Ø17 mm |
| Outer branch diameter (2) | Ø17.6 mm |
| Wall/step dimensions | 4 mm, 5 mm, 10 mm |
The stepped diameters across the three branch legs allow the connector to interface with tubing of different sizes at each port, giving it flexibility as a universal branching component across multiple line diameters within the same fluid system.
Material Properties: 60 Shore Silicone Rubber
The connector is molded from silicone rubber at 60 Shore A hardness, a mid-to-firm durometer that balances flexibility with structural stability at the Y-junction.
- Flexibility with Structural Retention: The 60 Shore hardness allows the connector to flex under tubing movement while holding its branched shape without excessive deformation.
- Color Consistency: Molded in black to RAL 9005 specification, supporting consistent visual identification across production batches.
- Chemical and Temperature Resistance: Silicone rubber offers strong resistance to a wide range of temperatures and many process fluids, supporting use across laboratory, industrial, and process fluid applications.
- Burr-Free Bore Finish: Internal bores are specified free of burrs and flash, supporting smooth, unobstructed flow through each branch.
Key Features
- Three-way Y-shaped branching design consolidates or splits flow paths in a single molded part.
- Multiple stepped bore diameters (Ø16mm, Ø13mm, Ø9mm) accommodate different tubing sizes per branch.
- 60 Shore A silicone hardness balances flexibility with dimensional stability.
- Burr-free internal bores support smooth flow and reduce contamination risk.
- Black RAL 9005 color for consistent visual identification.
- Compact reference weight of 82.6 g per unit.
Common Applications
- Laboratory tubing branch connections for fluid distribution.
- Process equipment Y-junctions for combining or splitting flow lines.
- Medical and diagnostic device tubing branch fittings.
- Industrial fluid handling systems requiring flexible branch connectors.
- General silicone tubing assembly where a molded Y-piece is required.
Why Choose Silicone for Y-Connector Fittings
Silicone rubber is a preferred material for Y-connector fittings because of its combination of flexibility, temperature stability, and resistance to aging compared to many general-purpose rubber compounds. These properties allow the connector to withstand repeated tubing connection and disconnection cycles, flex naturally with line movement, and maintain a reliable seal at each branch interface over its service life.
Custom Manufacturing Options
- Custom bore diameters and branch angle configurations beyond the standard Ø30mm/Ø16mm/Ø13mm/Ø9mm reference.
- Custom overall length and branch offset dimensions.
- Custom Shore hardness for different flexibility or sealing requirements.
- Custom color beyond standard black RAL 9005.
- Custom branch count or asymmetric Y-configurations for specialized routing needs.
FAQ
What is a Silicone Y-Connector used for?
A Silicone Y-Connector is used to connect three compatible tubing lines in a Y-shaped path. It can split one line into two branches, combine two lines into one outlet or redirect tubing in compact equipment assemblies when the port sizes match the tubes.
What does Silikon-Y-Hahn mean?
Silikon-Y-Hahn is a German product term for a silicone Y connector or silicone Y-type tubing connector. In this product context, it refers to a molded silicone component used for three-way tubing connection and flow distribution.
Can the port sizes be customized?
Yes. Main port inner diameter, branch port inner diameter, outer diameter, wall thickness and branch angle can be customized according to the tubing and assembly requirements. Correct port sizing is important for insertion force, retention and sealing contact.
What material is used for this Y-connector?
The product is made from silicone rubber. Silicone material is selected for flexibility, elastic recovery and clean handling. Final compound selection should consider contact media, temperature, pressure, cleaning method and required documentation.
Can this connector be used for liquid transfer?
It can be used for compatible liquid transfer when the silicone compound, port design and tubing fit match the working media and pressure condition. Material compatibility should be confirmed before use with oils, solvents, chemicals or special fluids.
Are samples available before bulk production?
Samples are available upon request. Sample preparation depends on confirmed port size, silicone compound, Shore A hardness, color, tooling status, inspection requirements and packaging method. A tubing sample or physical connector sample helps verify fit before batch production.
