Full title and description

SAE MA2103A — Hose assembly, metal, medium pressure, flareless, welded, straight to 90° fitting ends, metric. This technical standard specifies the configuration and general requirements for metric metal hose assemblies using flareless, welded connections with fitting end angles from straight to 90° intended for medium-pressure aerospace fluid systems.

Abstract

MA2103A defines the form, fitting-end geometry and general assembly approach for metric metal hose assemblies that use flareless, welded connections and include straight through 90° fitting ends. The document is short (informational/design standard length) and is intended to provide uniformity for suppliers, designers and maintenance organizations working with medium-pressure fluid lines in aerospace applications.

Scope

This standard applies to metric metal hose assemblies intended for medium-pressure aerospace fluid systems where flareless, welded connections are used and fitting-end configurations range from straight (0°) to 90°. It addresses the assembly form, fitting-end orientations and the use of flareless, welded joint construction to promote interchangeability and consistent assembly practice across suppliers and maintenance organizations.

Key topics and requirements

• Definition and designation of metric metal hose assemblies using flareless, welded fittings.
• Allowed fitting-end geometries and angular range (straight to 90°).
• Welded, flareless connection requirements and intent to standardize assembly methods for medium-pressure service.
• Compatibility considerations for mating components in metric fluid systems.
• Intended use in aerospace fluid and hydraulic systems — emphasis on form and interchangeability rather than detailed test methods.

Typical use and users

Engineers and designers of aerospace hydraulic and fluid systems, hose and fitting manufacturers, maintenance and overhaul organizations, quality and procurement teams specifying metric metal hose assemblies for medium-pressure applications, and technical libraries maintaining aerospace parts and installation standards.
