WEATHERHEAD

Weatherhead is a brand of hydraulic and pneumatic fittings, hose couplings, and connectors with a history dating back to the early 20th century. The brand is known for its extensive line of quick-connect couplings, hydraulic flange fittings, and needle valves, serving industries such as mobile equipment, industrial machinery, and fluid power systems. Weatherhead products are designed to meet SAE, ISO, and other industry standards for pressure ratings, material compatibility, and dimensional interchangeability. The product range includes brass and steel quick-connect couplings for air and hydraulic applications, crimpable hydraulic flange fittings in straight, 45°, and 90° elbow configurations, and needle valves for flow control. Weatherhead fittings are constructed from materials such as carbon steel and brass, with options for various thread types (NPT, BSPP, JIC) and sizes from 1/8 in to 2 in. The brand emphasizes reliability in high-pressure environments, with hydraulic flange fittings rated for working pressures up to 6000 psi depending on size and configuration. 3G Electric supplies a selection of Weatherhead products, including quick-connect air coupling bodies and hydraulic flange fittings, sourced to support maintenance, repair, and operations (MRO) requirements for plant engineers and procurement specialists. The inventory covers common sizes and configurations, enabling replacement of worn or damaged components in hydraulic systems, pneumatic tools, and fluid transfer lines. Weatherhead's universal interchange design for quick-connect couplings ensures compatibility with other brands using the same profile, simplifying field replacements. For hydraulic flange fittings, the crimpable design allows permanent attachment to hose assemblies using standard crimping equipment, providing a leak-resistant connection in high-vibration environments. 3G Electric's catalog includes part numbers and specifications to facilitate direct cross-referencing with existing equipment, reducing downtime during repairs.

Common Applications

  • Mobile hydraulic systems — Weatherhead hydraulic flange fittings (e.g., 12Z-G42) for hose assemblies in excavators and loaders
  • Pneumatic tool lines — Weatherhead quick-connect couplings (e.g., 430) for air supply connections in manufacturing plants
  • Industrial machinery — Weatherhead 45° elbow flange fittings (e.g., 20Z-G54) for hydraulic power units
  • Fluid transfer systems — Weatherhead straight flange fittings (e.g., 16Z-G20) for high-pressure oil lines
  • Maintenance and repair — Weatherhead quick-connect bodies (e.g., 580) for replacing worn couplings on pneumatic tools
  • Hydraulic press applications — Weatherhead 90° elbow flange fittings (e.g., 24Z-G84) for compact hose routing in tight spaces

Frequently asked questions

Common questions about WEATHERHEAD from 3G Electric.

What materials are Weatherhead hydraulic flange fittings made from?

Weatherhead hydraulic flange fittings, such as the 12Z-G42 and 20Z-G54, are constructed from carbon steel. This material provides strength and durability for high-pressure hydraulic systems. The fittings are designed for crimping onto hydraulic hose assemblies and are available in straight, 45°, and 90° elbow configurations to accommodate routing requirements.

Are Weatherhead quick-connect couplings interchangeable with other brands?

Yes, Weatherhead quick-connect couplings, like the 430 and 580 models, are designed with a universal interchange profile. This means they are dimensionally compatible with other brands that follow the same interchange standard, such as Aro, Dixon, and Foster. The brass construction and sleeve locking mechanism ensure reliable connection for pneumatic applications.

What is the maximum working pressure for Weatherhead hydraulic flange fittings?

Weatherhead hydraulic flange fittings are rated for working pressures up to 6000 psi, depending on the size and configuration. For example, the 16Z-G46 (1 in hose I.D.) and 24Z-G84 (1 1/2 in hose I.D.) are designed to handle high-pressure hydraulic systems. Always verify the specific pressure rating for the fitting size and hose assembly used.

What thread types are available on Weatherhead quick-connect couplings?

Weatherhead quick-connect couplings, such as the 430 model, feature male NPT (MNPT) threads. The 430 has a 3/8 in body size with 3/8-18 MNPT threads. Other models may offer female NPT or BSPP threads. The thread type is specified in the product details to ensure compatibility with existing system ports.

Can Weatherhead hydraulic flange fittings be used with any hose brand?

Weatherhead hydraulic flange fittings are designed for crimping onto hydraulic hoses. They are compatible with hoses that meet SAE 100R series specifications, provided the hose I.D. matches the fitting size. The crimpable design requires a crimping machine and proper die selection to achieve a secure, leak-free connection. Always follow the manufacturer's crimp specifications.
