Overview
ISO 7375-1:1986 is an international standard developed by the International Organization for Standardization (ISO) that specifies the dimensional requirements for coiled pipe assemblies used in pneumatic braking connections between motor vehicles and their towed units. Specifically, this part addresses the minimum dimensional conditions needed to ensure reliable and compatible pneumatic braking system connections within vehicle combinations.
This second edition, published in 1986, replaces the first edition from 1982. It focuses on the physical dimensions of coiled flexible pipes equipped with their connectors, which are critical to maintaining braking compatibility and ensuring optimal response time in pneumatic braking systems.
Key Topics
Scope and Application
ISO 7375-1 applies exclusively to spiral coiled pipe assemblies designed for pneumatic braking systems in motor vehicle and trailer combinations. It does not cover other types of thermoplastic tubing used in such systems.Dimensional Specifications
- Two standard types of coiled pipes are defined based on their effective length:
- Type 1: 4 meters
- Type 2: 4.5 meters
- The standard specifies parameters such as pipe length, maximum uncoiled length, and allowable ovalization (distortion) after spiral forming.
- Detailed figures illustrate the cross-sectional dimensions and connectors of the coiled pipes.
- Two standard types of coiled pipes are defined based on their effective length:
Performance and Compatibility
While Part 1 focuses on physical dimensions, a complementary Part 2 of ISO 7375 will address performance requirements such as durability and pressure resistance. Together, these parts ensure that all pneumatic brake connections maintain fast and reliable response times, crucial for vehicle safety.Design Flexibility
The standard allows manufacturers freedom regarding external pipe design, attachment methods, and auxiliary features like anti-kinking devices, provided the dimensional criteria are met.
Applications
ISO 7375-1:1986 is essential for manufacturers, designers, and maintenance professionals involved in:
- Automotive and trailer manufacturing where pneumatic brake lines must conform to international dimensions to guarantee interchangeability and operational safety.
- Fleet operators and service centers ensuring replacement and repair parts meet standardized dimensional tolerances to maintain braking system integrity.
- Safety inspectors and regulatory bodies verifying compliance with standardized brake connection specifications during vehicle certification or roadworthiness assessments.
This standard supports the smooth operation of pneumatic braking systems by facilitating:
- Consistent and compatible connections between motor vehicles and trailers.
- Minimized response time delays in pneumatic brake signals, enhancing overall road safety.
- Interchangeability of components among different manufacturers in global markets.
Related Standards
ISO 7375-1:1986 complements other international standards focused on vehicle braking system components and connections, including:
- ISO 7375-2 – Specifies the performance requirements for spiral coiled pipe assemblies with connectors used in pneumatic braking systems.
- ISO 1726 – Standardizes mechanical couplings between tractors and semi-trailers for towing safety and interoperability.
- ISO 1728 – Details pneumatic brake line fittings, connectors, and tubing specifications for reliable brake operation.
- ISO 4039 – Provides terminology and vocabulary related to braking in road vehicles and trailers for consistent communication.
Using ISO 7375-1 alongside these standards helps ensure a harmonized approach to pneumatic brake system design, manufacturing, and maintenance worldwide.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bodies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 7375/1 was prepared by Technical Committee ISO/TC 22,
Road vehicles.
This second edition cancels and replaces the first edition (ISO 7375/1-19821, of which
it constitutes a minor revision.
Users should note that all lntetnational Standard undergo revision from time to time
and that any reference made herein to any other International Standard implies its
latest edition, unless otherwise stated.
