Overview
EN ISO 13341:2025 - "Gas cylinders - Fitting of valves to gas cylinders" specifies safe, repeatable procedures for connecting valves to gas cylinders using ISO screw threads. It applies to valve/cylinder combinations conforming to ISO 11363-1 (taper threads) and ISO 15245-1 (parallel threads) and covers inspection, preparation and assembly practices for steel, aluminium alloy and certain composite cylinders. Annex A provides normative torque guidance for cylinders including composite types with steel or aluminium alloy neck bosses.
Key topics and technical requirements
- Scope and applicability: Procedures target ISO screw-thread valve-to-cylinder connections; recommendations can be applied to non-ISO threads when compatible guidance exists (see ISO/TR 11364).
- Inspection & preparation: Visual inspection of valve and cylinder threads, O‑ring sealing surfaces and cleaning of threads prior to valving (new requirement in this edition).
- Taper-thread valving: Guidance on threading, use of sealants (e.g., tape or paste), soft metal cones or PTFE cones, and controlled torquing.
- Parallel-thread valving: Specific procedures for achieving leak-tight assemblies and correct sealing practice for parallel connections.
- Valve torquing & verification: Torque ranges and limits (given in Annex A) must be observed; exceeding maximum torque can overstress valve inlets or cylinder necks. Tools must fit valves, protect surfaces, and be periodically checked for accuracy.
- Alignment & mechanical constraints: Axis alignment of valve and cylinder; procedures for cylinders with fixed shrouds or welded bosses to achieve proper valve orientation.
- Material-specific precautions: Lower torques and thermal considerations for aluminium alloy and composite cylinders; avoid valving at elevated temperatures that could induce residual stresses.
- Manufacturer instructions: Valve and cylinder manufacturers’ specific recommendations take precedence when they differ from this standard.
Applications and users
EN ISO 13341:2025 is essential for:
- Cylinder manufacturers and assemblers
- Valve manufacturers and suppliers
- Gas filling and distribution companies
- Cylinder inspection/repair workshops and conformity assessors
- Safety engineers, maintenance technicians and regulators
Use cases include final assembly at production, field re-valving, service/repair operations, and quality-assurance procedures at gas filling plants.

4 General requirements and recommendations
Gas cylinders and valves shall be connected so that when in use the combination is gas tight and the valve
cannot be removed inadvertently from the cylinder.
Standards exist to allow for the assessment of the condition of both cylinders and valves, e.g. ISO 22434 and
ISO 18119. Their requirements should be taken into account before assembly, especially to verify that the
threads are in an acceptable condition.
The tools used to screw the valve into the gas cylinder shall fit the valve properly and the gas cylinder shall
be secured against rotation during the torquing process.
The tools shall not cause damage to either the valve or the cylinder. Additional instructions given by the
cylinder manufacturer shall be followed.
In particular for composite cylinders, which are less able to withstand the stresses typically applied to
metallic cylinder

The standard EN ISO 13341:2025, titled "Gas cylinders - Fitting of valves to gas cylinders," presents a comprehensive framework focused on the critical procedures for connecting cylinder valves to gas cylinders. The standard's scope explicitly outlines its applicability to all valve and cylinder combinations that utilize ISO screw threads as specified in ISO 11363-1 and ISO 15245-1. This clear delineation ensures that users can effectively understand the specific contexts in which the standard is relevant and can apply it appropriately. One of the key strengths of this standard is its thorough approach to detailing the procedures and practices for inspection and preparation prior to valving. By addressing both taper and parallel screw threads, the standard caters to a broad range of gas cylinder configurations, making it a versatile and essential reference for manufacturers and users alike. Furthermore, the inclusion of torque values in Annex A for steel and aluminium alloy gas cylinders, along with composite cylinders featuring steel or aluminium alloy neck bosses, enhances the practical utility of the standard. These precise specifications ensure that connections can be made safely and reliably, thereby minimizing risks associated with gas cylinder operation. The relevance of EN ISO 13341:2025 extends beyond the immediate applications outlined within its scope. The document acknowledges that the procedures and practices specified can be beneficially applied to other valve-to-cylinder screw thread connection systems. This aspect broadens the standard's impact, suggesting that stakeholders in various industries can adapt its guidelines to their specific needs. The reference to ISO/TR 11364 further strengthens this point by providing additional context on valve to gas cylinder threads used globally, including thread identification codes and compatibility assessments with ISO threads. The incorporation of detailed guidance on taping procedures and torque values for non-interchangeable threads enhances the standard's usability and effectiveness across diverse applications. In summary, EN ISO 13341:2025 stands out as a pivotal standard that not only defines essential practices for the safe and effective fitting of valves to gas cylinders, but also extends its relevance to a wider audience through its adaptable procedures and comprehensive guidance. Its strengths lie in its detailed specifications, practical applicability, and the clarity of its scope, making it an indispensable resource in the realm of gas cylinder safety and maintenance.

EN ISO 13341:2025 표준 문서는 가스 실린더와 밸브 연결에 대한 프로세스를 구체적으로 명시하고 있습니다. 이 표준은 ISO 나사산 기준에 따라 연결된 모든 밸브 및 실린더 조합에 적용되며, ISO 11363-1 및 ISO 15245-1에 명시된 사양에 따라 실린더 밸브를 연결할 때 따라야 할 절차를 정의합니다. 이 표준의 강점은 실린더의 나사산 종류에 따라 절차와 준비 과정을 명확하게 규정하고 있다는 점입니다. 특히 테이퍼 형태와 평행 나사산 모두에 대한 검사 및 준비 절차가 포함되어 있어, 다양한 유형의 가스 실린더에 적용할 수 있습니다. 또한, Annex A에서는 강철 및 알루미늄 합금으로 제작된 가스 실린더에 대한 토크 값을 명시하고 있어, 안전하고 효율적인 연결을 보장합니다. EN ISO 13341:2025는 다른 밸브와 실린더 간의 나사산 연결 시스템에도 쉽게 적용할 수 있는 절차와 관행을 제공하므로, 해당 분야의 전문가들이나 관련 산업에서 큰 도움이 될 것입니다. 또한, ISO/TR 11364에서는 전 세계에서 사용되는 밸브와 가스 실린더 나사산에 대한 리스트를 제공하며, 이 표준의 토크 값 및 테이핑 절차를 사용할 수 있는지에 대한 정보도 포함되어 있어, 표준의 활용성을 한층 높입니다. 이 표준은 가스 실린더와 밸브 간의 안전하고 효율적인 연결을 위한 필수 지침이므로, 가스 실린더 관련 기업 및 사용자는 이를 적극적으로 참고하여 안전성을 증대시킬 수 있습니다. EN ISO 13341:2025는 가스 안전과 관련된 품질 관리 기준을 준수하며, 이러한 이유로 가스 실린더 산업에서의 중요성이 더욱 강조됩니다.
