Buy screw-to-connect couplings with poppet valve from the HT series from STAUFF in the online shop

The screw-to-connect couplings with poppet valve from the HT series from STAUFF are specially designed for use in mobile high-pressure hydraulic systems. They consist of a coupling sleeve with a winged screw sleeve and a coupling plug with an external thread. The wing nut enables convenient operation - even when wearing work gloves or in hard-to-reach areas of tippers, trailers and agricultural equipment.

The robust design ensures a secure connection at operating pressures of up to 350 bar. Once fully bolted, all internal components have minimal play, significantly reducing the risk of material fatigue. The design also prevents the occurrence of "brinelling" - permanent indentations on the surface of the connector, which can occur in extreme applications with conventional plug-in couplings.

Materials and surfaces

The HT couplings are made of high-quality steel and are designed for use in harsh conditions. The zinc/nickel surface coating offers maximum protection against corrosion - even when used intensively on construction sites or in the agricultural sector.

  • Steel: high mechanical strength and resilience

  • Zinc/nickel coating: corrosion protection class K5 in accordance with VDMA 24576

  • poppet valve: controlled flow and reliable sealing

Product variants and sizes

The HT series is available in two nominal sizes and is designed for operating pressures of up to 350 bar. The coupling can also be safely connected and disconnected under residual pressure.

Available options:

  • Nominal sizes: 19 and 25 (3/4" to 1")

  • Maximum nominal flow rate: up to 283.5 l/min

  • Interchangeability according to market standards

Applications and areas of use

The HT series screw-to-connect couplings are designed for hydraulic systems that have to function reliably under mobile and heavy-duty conditions. They are used in the following areas in particular:

  • Hydraulic tippers

  • Trailers of commercial vehicles

  • Agricultural equipment

  • Construction machinery

  • Mobile tools with high pressure requirements

Advantages and unique selling points

The HT series from STAUFF offers a combination of practical operation, high load capacity and effective corrosion resistance. It is the preferred choice for mobile high-pressure connections in demanding environments.

  • Wing screw sleeve for easy handling - even when wearing gloves

  • Can be coupled under residual pressure

  • Minimised play of internal components reduces material fatigue

  • No brinelling - ideal for pulsating applications

  • Corrosion protection class K5 due to zinc/nickel coating

  • High availability and fast delivery from the STAUFF programme

Certifications and standards

The HT series couplings fulfil the requirements of international standards for high-pressure screw-to-connect couplings. The surface treatment fulfils the requirements for reliable corrosion protection in accordance with VDMA 24576.
