Parker A4N0347D1K Piston Accumulator 347 Cu in Sae 20

Product Description

The PARKER A4N0347D1K is a piston-style hydraulic accumulator designed to store and release pressurized hydraulic fluid in industrial and mobile hydraulic systems. With a fluid capacity of 347 cubic inches and a gas capacity of 357 cubic inches, this accumulator handles energy storage, shock absorption, and flow supplementation duties in demanding hydraulic circuits. The port thread size is SAE 20, which is standard for high-pressure hydraulic line connections. At 61 pounds, this is a substantial unit suited for fixed or mobile equipment installations. Licensed hydraulic system technicians and industrial maintenance professionals are the typical installers.

This accumulator is applicable in hydraulic power units, heavy equipment, and industrial machinery where the system requires pressure maintenance, surge dampening, or emergency fluid backup. Piston accumulators are commonly selected over bladder or diaphragm styles when large fluid volumes, high flow rates, or wide temperature ranges are required. The SAE 20 port makes integration into existing hydraulic plumbing straightforward using standard JIC or SAE straight-thread fittings.

Key Features

• Fluid capacity of 347 cubic inches for substantial hydraulic energy storage
• Gas capacity of 357 cubic inches supports effective precharge volume
• SAE 20 port thread size for compatibility with standard high-pressure hydraulic fittings
• Piston design accommodates high flow rates and large fluid volume displacement
• Robust construction at 61 pounds, built for industrial-duty applications

Compatibility

Designed as an OEM-style piston accumulator for hydraulic systems requiring an SAE 20 port connection with a fluid capacity of 347 cubic inches. Confirm system working pressure and precharge requirements against the unit specification sheet before installation.

Installation Notes

Installation should be performed by a qualified hydraulic systems technician. Depressurize and isolate the hydraulic circuit completely before removing or installing any accumulator. Precharge the gas side with dry nitrogen only — never use oxygen or compressed air. Follow applicable industry safety standards and the equipment manufacturer's service documentation for mounting orientation, precharge pressure, and torque specifications.
