HANSEN

HANSEN is a manufacturer of quick-connect couplings, valves, and related fluid-handling components, with a product line that includes the FF Series, HK Series, and FLO-TEMP Series. The brand is known for its push-to-connect and sleeve-locking coupling designs, which are used in hydraulic, pneumatic, and gas-handling applications. HANSEN couplings are available in steel, brass, and other materials, with thread sizes ranging from 1/4 in to 1-1/16 in and flow rates up to 105 lpm. The product range also includes oxygen hose quick-disconnect couplings with color-coded green sleeves for medical or industrial gas service, as well as socket trays and wrench racks for tool organization. HANSEN components are built to standard industrial specifications, with no proprietary certifications beyond those implied by the product types (e.g., push-to-connect couplings for hydraulic systems). 3G Electric stocks 167 SKUs from HANSEN, covering coupling plugs, coupling bodies, and accessories. These products are suitable for plant engineers and maintenance managers who need reliable fluid-transfer connections in hydraulic circuits, pneumatic systems, or gas-delivery lines. The FF Series, for example, uses a push-to-connect locking mechanism that allows for quick line changes without tools, while the oxygen couplings feature a sleeve-lock design to prevent accidental disconnection. 3G Electric supports the HANSEN line by offering global shipping, technical specifications for each SKU, and the ability to source parts for both standard and specialized applications. Buyers can select based on coupling size, thread type, material, and flow rate, ensuring compatibility with existing equipment. The brand’s focus on quick-disconnect technology makes it relevant for industries such as manufacturing, oil and gas, and medical gas systems, where downtime reduction and connection security are priorities.

Frequently asked questions

Common questions about HANSEN from 3G Electric.

What materials are used in HANSEN FF Series quick-connect couplings?

HANSEN FF Series quick-connect couplings are available with steel bodies, as seen in models like the 19FFP106UN and 16FFS75. Steel provides durability for hydraulic applications with pressures up to 3000 psi (depending on size). Some HANSEN couplings may also be offered in brass or stainless steel for corrosion resistance, but the FF Series primarily uses steel for standard hydraulic service.

How do HANSEN push-to-connect couplings differ from sleeve-lock couplings?

HANSEN push-to-connect couplings, such as those in the FF Series, use a locking mechanism that engages when the plug is inserted into the body, requiring no additional action to secure the connection. Sleeve-lock couplings, like the oxygen quick-disconnect plugs (e.g., MPN 08A), require the user to pull back a sleeve to connect or disconnect, providing a more positive lock for gas applications. The choice depends on the need for speed versus security in the connection.

What is the maximum flow rate for HANSEN 3/4 in FF Series couplings?

The HANSEN 19FFP106UN, a 3/4 in FF Series coupling plug, has a maximum flow rate of 105 lpm (approximately 27.7 gpm). This rating is based on the coupling size and internal bore design. For smaller sizes, such as the 3/8 in 10FFP75UN, the maximum flow rate is 29 lpm. Always verify flow requirements against the specific model's specifications to ensure adequate performance.

Are HANSEN oxygen couplings compatible with medical gas systems?

HANSEN oxygen quick-disconnect couplings, such as the 08A (5/16 in hose barb) and 07A (1/4 in hose barb), are designed for oxygen service and feature a green color code for identification. They use a sleeve-lock mechanism and are typically used in medical gas or industrial oxygen systems. However, compatibility with specific medical gas standards (e.g., NFPA 99) should be confirmed by the end user, as HANSEN does not explicitly list medical certifications on these products.

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

HANSEN quick-connect couplings are available with various thread types, including UNF (Unified Fine) and NPT (National Pipe Thread). For example, the 04R oxygen plug uses a 9/16 in UNF thread, while the FF Series plugs like the 10FFP75UN use a 3/4 in-16 thread. Thread sizes range from 1/4 in to 1-1/16 in, depending on the model. Always match the thread type and size to your system's connections to ensure a leak-free fit.
