About Parker

Parker Hannifin, commonly referred to as Parker, is a global manufacturer of motion and control technologies, with a product portfolio that spans hydraulic, pneumatic, and electromechanical systems. The company's origins date back to 1918, when Arthur L. Parker founded the Parker Appliance Company in Cleveland, Ohio, initially producing pneumatic braking systems for trucks. Over the ensuing decades, Parker expanded into hydraulic components, becoming a major supplier to industrial, mobile, and aerospace sectors. Today, Parker's product lines include directional control valves, pressure control valves, hydraulic filters, hose fittings, and instrumentation fittings, all engineered to meet rigorous performance standards. The components supplied by 3G Electric are selected for their technical specifications and compatibility with common industrial systems, covering applications from high-pressure hydraulic circuits to precision pneumatic controls.

Within the Parker line, 3G Electric carries a range of components that address the needs of plant engineers and maintenance professionals. The directional control valve series D1VW, for instance, is designed for NG06 (CETOP 03 / NFPA D03) mounting patterns and offers flow rates up to 80 l/min, with a low pressure drop that contributes to energy efficiency. These valves are available with NBR seals and can be specified with explosion-proof solenoids that are ATEX certified, making them suitable for hazardous environments. For fluid conveyance, Parker's hydraulic fittings include steel threaded plugs rated to 4,500 psi, crimp hose fittings with NPTF connections for -8 hose dash sizes, and double-ferrule compression fittings in stainless steel, such as the A-Lok series, which are compatible with Swagelok fittings. These components are manufactured to precise tolerances, ensuring leak-free connections in high-pressure systems.

Parker's filtration technology is represented by replacement filter elements for WPF Series pressure line filters, featuring Ecoglass media and 5-micron filtration, with a maximum pressure rating of 7,000 psi and flow capacity up to 60 gpm. This level of filtration is critical for protecting downstream components from contamination. Additionally, Parker's extreme-pressure instrumentation fittings, including hex nipples and plugs in 316 stainless steel, are rated for pressures up to 6,400 psi, suitable for high-pressure hydraulic and pneumatic systems. These products are built to withstand demanding conditions, with materials and designs that meet industry standards such as ISO 1219 and CETOP mounting specifications. 3G Electric supports the Parker line by offering a broad inventory, technical documentation, and global shipping, enabling procurement specialists to source these components with confidence. The focus is on providing functional, specification-driven products that integrate seamlessly into existing systems, without the need for extensive modification.

Frequently asked questions

Common questions about Parker from 3G Electric.

What are the key specifications of the Parker D1VW directional control valve series?

The Parker D1VW series directional control valves are designed for NG06 (CETOP 03 / NFPA D03) mounting patterns, providing a compact solution for hydraulic systems. They offer a maximum flow rate of 80 l/min, with a low pressure drop due to optimized flow paths, which contributes to energy savings. The valves are available with NBR seals, suitable for mineral oils and other compatible fluids. For hazardous environments, they can be equipped with explosion-proof solenoids that are ATEX certified. These valves are typically used in applications requiring precise fluid flow direction, such as machine tools, injection molding, and material handling equipment.

Are Parker A-Lok compression fittings compatible with Swagelok fittings?

Yes, Parker A-Lok double-ferrule compression fittings are designed to be compatible with Swagelok fittings, as both use a similar two-ferrule design that creates a reliable, leak-tight seal on tubing. The Parker A-Lok series, such as the 6NU6-316 nut for 3/8 inch OD tubing, is manufactured in stainless steel, offering corrosion resistance and durability. This compatibility allows for mixing components from both brands in a single system, provided the tubing dimensions and ferrule sizes match. It is important to verify the specific part numbers and tubing specifications to ensure proper fit and performance.

What is the maximum pressure rating for Parker hydraulic hose plugs?

Parker hydraulic hose plugs, such as the 1/4 HHP-SS, are rated for a maximum working pressure of 7,200 psi at 70°F. These plugs are constructed from stainless steel, providing corrosion resistance and strength for high-pressure applications. They are used to seal open ports or hose ends in hydraulic systems, preventing leakage and contamination. The 1/4 inch fitting size with 1/4-18 NPT threads ensures a secure connection. Always verify the pressure rating of the plug against the system's operating pressure to ensure safe and reliable operation.

What is the filtration rating of Parker WPF Series filter elements?

Parker WPF Series filter elements, such as the 941036Q, feature Ecoglass media with a 5-micron filtration rating. This level of filtration is effective in removing particulate contaminants from hydraulic fluid, protecting sensitive components like valves and pumps. The element is rated for a maximum pressure of 7,000 psi and a maximum flow of 60 gpm, making it suitable for high-pressure hydraulic pressure line applications. The single-length housing design simplifies replacement, and the Ecoglass media offers high dirt-holding capacity and low pressure drop, extending service life and reducing maintenance frequency.

Are Parker extreme-pressure fittings available in stainless steel?

Yes, Parker extreme-pressure instrumentation fittings are available in 316 stainless steel, which provides excellent corrosion resistance and mechanical strength. For example, the hex nipple (SKU 12-12 MHLN-SS 3.0) is a 316 stainless steel fitting with 3/4 inch male NPT connections on both ends, rated for 6,400 psi. Similarly, the plug (SKU 3 HP5ON-SS) is a 316 stainless steel plug with a 3/8 inch male thread, rated for 6,000 psi. These fittings are designed for high-pressure hydraulic and pneumatic systems, ensuring reliable sealing and durability in demanding environments.
