ISO 8637-2 Cone Reference Connector
Product Overview
Blood circuit connectors used in extracorporeal treatment systems must provide reliable mechanical engagement with their intended mating components. The geometry of the mating interface is important when evaluating connector compatibility and performance under defined laboratory conditions.
The KP-8637F4 Cone Reference Connector provides a standardized conical mating surface for testing blood socket connectors associated with ISO 8637-2. Its defined geometry allows laboratories to establish a consistent mechanical interface when arranging connector tests.
Unlike a dimensional inspection gauge, which is used to assess geometric engagement against dimensional limits, a reference connector serves as the specified mating component within a connector test arrangement. The required test conditions and measurements are provided by the associated test equipment and procedure.
The KP-8637F4 is manufactured from 440C stainless steel, with a specified hardness of HRC 58–60 and critical surface roughness not exceeding Ra 0.8 μm. Its compact construction makes it suitable for integration into compatible laboratory fixtures and connector test arrangements.

The defined cone dimensions establish the mating geometry used for reference connector testing. Selection should take account of the connector design, dimensional requirements and applicable test procedure.
Role of the Cone Reference Connector
In connector testing, the mating component must have defined dimensions so that the test is not affected by uncontrolled variations in the opposing connector.
The KP-8637F4 addresses this requirement by providing a precision-defined conical interface.
Reference Mating Geometry
The connector features a 6:100 taper with specified cone dimensions and tolerances. This geometry provides a reference mating surface for the blood socket connector under test.
Consistent Connector Engagement
A reference connector helps establish a defined mating condition when specimens are tested using the same geometry and appropriate laboratory procedure.
Integration with Test Equipment
The KP-8637F4 can serve as the mating component within a compatible connector test fixture. The required force, pressure or other test conditions are applied and measured by the appropriate external equipment.
The reference connector itself does not measure pressure, leakage, axial force or torque.
How the Reference Connector Is Used
The KP-8637F4 functions as a reference mating component within a connector test setup.
A typical laboratory arrangement involves selecting the appropriate reference connector geometry, securing the reference component in a compatible fixture and mating it with the blood socket connector under test.
The laboratory then carries out the applicable test procedure using the required external equipment and controlled test conditions.
The reference connector contributes the defined mechanical mating interface. Other parts of the test arrangement may provide pressure regulation, force application, measurement or observation, depending on the test being performed.
For reliable test results, the mating alignment, fixture arrangement and connector preparation should correspond to the applicable procedure.
ISO 8637-2 Standard and Test Application
ISO 8637-2 specifies requirements for disposable extracorporeal blood and fluid circuits and associated accessories used with haemodialysis equipment.
These systems are used in extracorporeal blood treatment therapies, including haemodialysis, haemodiafiltration and haemofiltration. Connections between blood circuit components and their intended mating interfaces are subject to applicable dimensional and functional requirements.
The KP-8637F4 provides a defined conical reference interface for blood socket connector testing associated with ISO 8637-2.
A complete connector conformity assessment may require additional procedures to evaluate leakage, mechanical separation or other connection characteristics. The reference connector forms part of the relevant test arrangement and does not replace the equipment needed to apply or measure those conditions.
Typical Laboratory Applications
| Blood Circuit Connector Development | Reference mating interface for evaluating the connection geometry and compatibility of blood socket connector designs. |
| Medical Device Testing Laboratories | Integration into connector test arrangements requiring defined ISO 8637-2 conical reference geometry. |
| Manufacturing Quality Verification | Supporting controlled connector evaluation during product validation and quality-assurance activities. |
| Testing Fixture Development | Reference mating component for designing or adapting compatible blood socket connector testing fixtures. |
