ISO 8637-2 Conical Gauge
Product Overview
Reliable connections in extracorporeal blood circuits depend on accurately manufactured mating surfaces. Conical connectors must maintain their specified geometry to achieve the intended engagement with corresponding blood ports.
The KP-8637F3 Conical Gauge provides a precision-defined mating reference for inspecting the conical geometry of blood socket connectors associated with ISO 8637-2.
Its 6:100 taper geometry and specified 5 N inspection force support controlled assessment of dimensional engagement. By using a reference gauge with defined dimensions, laboratories and manufacturers can evaluate connector geometry against the applicable dimensional requirements.
The gauge is manufactured from 440C stainless steel, with a specified Rockwell hardness of HRC 58–60 and a surface roughness not exceeding Ra 0.8 μm on critical surfaces.
Designed as a mechanical inspection component, the KP-8637F3 does not require an electronic measuring system for its intended gauging function.

The defined conical geometry provides a reference for dimensional inspection of blood socket connectors under the specified gauging conditions.
Conical Dimensional Inspection
The KP-8637F3 is used to examine the mating geometry of blood socket connectors. The inspection primarily concerns three characteristics:
Conical Geometry
The gauge incorporates a defined 6:100 taper, allowing the mating cone geometry to be evaluated against specified dimensional limits.
Engagement Position
The engagement between the reference cone and the connector is relevant to determining whether the conical interface falls within the permitted dimensional range.
Dimensional Consistency
A defined gauge geometry provides a consistent reference for inspection activities involving connector development, production verification and quality control.
Dimensional inspection is distinct from functional testing. Liquid leakage, air leakage, separation resistance and other connection performance characteristics require the appropriate test procedures and equipment.
The 5 N Inspection Force
The 5 N inspection force is an important test condition for the KP-8637F3.
The force applied during inspection affects the engagement between the gauge and the connector. Using a specified force helps establish a consistent inspection condition when evaluating connector geometry.
The 5 N value represents the inspection force, not the measuring range of a force tester.
Gauge engagement and dimensional acceptance should be assessed using the procedure required by the applicable ISO 8637-2 edition.
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.
Connector dimensional requirements help establish mechanical compatibility between blood circuit components and their intended mating interfaces.
The KP-8637F3 supports conical dimensional inspection associated with these requirements through its defined reference geometry and 5 N inspection condition.
The gauge is intended for dimensional verification and should not be used as a substitute for separate leakage or mechanical performance tests required for the complete connector assembly.
Typical Laboratory Applications
Compliance & Regulatory Assurance
The KP-8637F3 Conical Gauge is designed for dimensional inspection of blood socket connectors in accordance with the relevant requirements of ISO 8637-2. Its defined 6:100 taper geometry, 5 N inspection condition, and precision-machined 440C stainless steel construction support consistent evaluation of connector dimensions and engagement.
The gauge serves as a dimensional inspection reference within the applicable test procedure. Complete connector conformity assessment must also address any required leakage, mechanical integrity and connection performance tests specified by the relevant standard edition.
