What Parker Hannifin makes

Parker-Hannifin is a diversified motion and control manufacturer that builds engineered components across eight core technologies: hydraulics, pneumatics, electromechanical systems, filtration, fluid and gas handling, process control, engineered materials (sealing and shielding), and climate control. The company organizes this work into two reportable segments, Diversified Industrial and Aerospace Systems, and sells into roughly 1,100 markets, from off-highway and transportation equipment to aircraft, energy, HVAC, and refrigeration.

For automotive and transportation buyers, most of the relevant work sits in Parker's Engineered Materials Group and its fluid connectors and hydraulics divisions. On the electrification side, Parker supplies sealing for inverter, converter, and control-box housings, seals for battery and fuel-cell housings and e-axles, EMI shielding, and thermal gels and pads for heat dissipation. Its transportation liquid-cooling products are built for the pressure, temperature, and weight requirements of battery, inverter, and e-motor cooling circuits. Alongside the e-mobility portfolio, Parker continues to supply O-rings and engineered seals for internal-combustion applications, plus fluid connectors, hoses, and hydraulic components used across off-highway and commercial vehicles. This breadth is why the company describes itself through motion and control technologies rather than a single product line.

Financial performance

Parker reported record results for fiscal 2026, the year ended June 30, 2026. Net sales rose 8.3% to $21.5 billion, with organic sales up 6.6%. Reported segment operating margin increased 150 basis points to 24.5%, and adjusted segment operating margin reached a record 27.3%. Net income was $3.649 billion, adjusted diluted earnings per share rose 18% to a record $32.31, and operating cash flow hit a record $4.364 billion, or 20.3% of sales. Total backlog reached a record $12.8 billion, with aerospace backlog alone at a record $8.5 billion.

The prior year set the same pattern at a smaller base: fiscal 2025 net sales were $19.85 billion with a 23.0% reported segment operating margin and $3.776 billion of operating cash flow. Parker raised its annual dividend 11% in fiscal 2026, its 70th consecutive fiscal year of increases, one of the longest such streaks in the S&P 500. In February 2025, Moody's upgraded Parker's senior unsecured rating to A3 from Baa1 with a positive outlook, citing continued margin expansion and low leverage.

Ownership and history

Arthur L. Parker founded the Parker Appliance Company in Cleveland in 1917. The business merged with Hannifin Manufacturing in 1957 to become Parker Hannifin, went public in 1964, and now trades on the New York Stock Exchange under the ticker PH. It is an S&P 500 company and ranked #216 on the 2024 Fortune 500. Headquarters are at 6035 Parkland Boulevard in Mayfield Heights, Ohio, a Cleveland suburb.

Leadership per the company's own filings: Jennifer A. Parmentier is Chairman and Chief Executive Officer, having become CEO in January 2023 and Chairman in January 2024; Todd M. Leombruno is Executive Vice President and Chief Financial Officer; and Andrew D. Ross is President and Chief Operating Officer. Parker has stayed acquisitive: it closed the Curtis Instruments electrification deal and, during fiscal 2026, agreed to acquire Filtration Group Corporation and CIRCOR's Commercial and Defense Aerospace business.

Certifications and quality

Parker operates quality management systems across a large multi-plant footprint rather than under one corporate certificate. Its automotive-facing divisions, including the Fluid Control Division and Instrumentation Products Division, hold IATF 16949:2016 certification covering automotive, truck, and heavy-equipment applications, the standard that governs the production part approval discipline OEMs expect. Parker Aerospace works to AS9100, and numerous divisions and sites carry ISO 9001. The company also publishes a Global Supplier Quality Requirements Manual that requires its own suppliers to meet ISO 9001, IATF 16949, or the applicable AS9100/AS9110/AS9120 standard, which is a useful signal of how it runs its supplier base. These are the certifications the company posts for its divisions; scope and dates vary by site.

Known customers

Parker does not publish a named automotive OEM customer roster, which is normal for a component supplier serving many programs under confidentiality. What it does document is the shape of the demand:

Because these are program-type and market-level facts from Parker's own filings and division pages, they describe what Parker supplies, not a specific named-account list. Buyers evaluating Parker for a new program should expect division-level engagement rather than a single account team.
