Parker AD280B25T9A1 Diaphragm Accumulator 3620 Psi

Product Description

The PARKER AD280B25T9A1 is a hydrin diaphragm accumulator designed for hydraulic system applications requiring reliable pressure storage, energy management, and fluid surge dampening. The unit holds a capacity of 170 pounds and is rated to a maximum working pressure of 3,620 psi, making it suitable for demanding industrial and fluid-power installations. Standing 10.47 inches high with a 6.63-inch diameter, it fits into compact system layouts without sacrificing performance. The diaphragm is constructed from Hydrin, an ethylene oxide-epichlorohydrin elastomer known for its resistance to hydraulic fluids and moderate-temperature service. Installation is performed by licensed hydraulic technicians or qualified fluid-power specialists.

This accumulator is applied in hydraulic circuits where pressure fluctuation control, energy storage, or shock absorption is required. Typical installations include industrial machinery, mobile equipment hydraulics, and process systems that demand consistent pressure maintenance between pump cycles. The 8 SAE port thread connection integrates directly with standard SAE hydraulic fittings commonly found in these systems. It is suitable for both new system builds and replacement service on existing hydraulic circuits operating within the rated pressure envelope.

Compatibility

Designed as an OEM-style replacement or new-installation diaphragm accumulator for hydraulic systems plumbed with 8 SAE port thread connections and operating at pressures up to 3,620 psi.

Installation Notes

Installation and service of hydraulic accumulators must be performed by qualified fluid-power technicians familiar with high-pressure hydraulic systems. Before removing or installing the unit, fully depressurize and discharge the hydraulic circuit and relieve any stored gas precharge in accordance with the system manufacturer's procedures and applicable safety codes. Use properly rated SAE hydraulic fittings and torque hardware according to the fitting manufacturer's specifications. Never exceed the 3,620 psi maximum working pressure rating of this accumulator.
