Series IA

The push-fit couplings with cone valve from the IA series from STAUFF are a tried-and-tested solution for the quick, tool-free coupling and uncoupling of tube and hose lines in hydraulic systems. They consist of a coupling plug and a coupling sleeve and are standardised in accordance with ISO 7241-1 Series A. The IA series is available in eight sizes from DN 6 to DN 51 and therefore covers a wide range of applications - from mobile machines to stationary industrial systems.

Thanks to their robust design, the integrated locking system and the high-quality zinc/nickel surface coating, IA couplings are particularly corrosion-resistant and durable. They are considered the reference coupling in agricultural engineering and are also suitable for demanding industrial applications.

The IA series offers a wide range of nominal sizes and is designed for operating pressures of up to 350 bar - depending on the respective coupling size. The burst pressure corresponds to at least four times the operating pressure and ensures additional safety.

Available options:

• Nominal sizes: 06, 10, 12, 19, 25, 31, 38, 51 (1/4" to 2")

• Interchangeability according to ISO 7241-1 Series A

• Compatibility with HP series coupling plugs

• Can also be used in confined machine areas

The IA series from STAUFF offers a combination of standard-compliant design, high corrosion resistance and practical functionality. It is the preferred choice for hydraulic connections in agricultural engineering and beyond.

• Cone valve for controlled flow

• Integrated locking system for secure connection

• High safety factor: burst pressure ≥ 4 × operating pressure

• Compact design for use in confined machine areas

• Corrosion protection class K5 thanks to zinc/nickel coating

• Compatible with commercially available systems according to ISO 7241-1 A

• High availability and fast delivery from the STAUFF programme

Series IA couplings fulfil the requirements of the international standard ISO 7241-1 Series A. This ensures problem-free combination with standard market systems.
