BRASS ARO TYPE COUPLERS Aro 210 Type Coupler

Key Features & Specs

Construction & Materials

• Coupler bodies: brass (durable, corrosion-resistant)

• Nipples/plugs: typically steel, often case-hardened or zinc-plated for wear resistance

• Seals: nitrile (Buna‑N) standard; optional materials available

• Locking mechanism: usually 4‑ball system for reliable engagement

Pressure & Temperature

• Standard working pressure: approx. 300 psi

• Temperature range: from −40 °C up to +120 °C (approx.)

• Some versions rated to 250 psi or customized per spec

Flow Performance

• Flow around 25 ft³/min (~28 SCFM) for 1/4″

• Higher flow variants exist depending on design and size

Thread & Connection Options

• Common endports:

  • 1/4″ Male NPT (1/4‑18)

  • 1/4″ Female NPTF

  • 3/8″ Hose Barb

  • Push‑Lok hose barb

  • Male/female pipes, BSP variants also available

For example:

• Lawson Products (item #1593465): 1/4″ body, male 1/4‑18 NPT, brass, 300 psi, flow ~25 ft³/min, length 2.13″, hex 3/4″

• Lawson (item #1267535): 1/4″ body, 3/8″ hose barb, brass, same pressure, length ~2.47″

• Topring manual coupler: steel, accepts ARO‑210 plugs, 250 psi, airflow ~28 SCFM, -40 to +107 °C

Standard Benefits & Features

• Interchangeable with Parker 50 Series, Hansen 210, Tomco A100—common in pneumatic systems

• Integral sleeve guard: helps prevent accidental disconnection

• High‑flow tubular valve design: minimises pressure drop

• Dual shut‑off valves available (e.g. both in coupler and nipple) to reduce fluid/air loss
