Parker makes the hidden parts that move, seal, filter, cool and control machines and aircraft. Industrial equipment still supplies most of the sales, while aircraft parts and repair work are taking a larger share. The pattern is simple: win a place inside long-lived equipment, then keep selling what that equipment needs to stay working.

Flow and Process Control
Parker's pipes, fittings, pumps and valves produced $4.810B in FY2026, up 6.5%. Watch factory and data-center construction, equipment maintenance and rule changes that force cooling systems to use different gases.
Competes with Fittings, Valves and Regulators (Swagelok) · ASCO Fluid Control (Emerson)
In plain English
Inside a factory, liquids and gases must arrive at exactly the right place, pressure and cleanliness. Parker supplies the hoses, tubes, fittings, small pumps, valves and controls that make this happen—like the plumbing and taps of an industrial building, only built for harsher jobs.
Chip factories, processing plants, energy sites and makers of heating and cooling equipment pay for parts when they build, expand or repair their systems. Parker sells directly for tailored assemblies and through distributors for stocked parts. Once a design is approved, reliability and the cost of stopping production encourage repeat purchases.
Motion Systems
The parts that make machinery move delivered $3.580B in FY2026, up 7.2% but still below FY2024. Watch whether the industrial recovery broadens and whether electric controls add more work than older fluid-powered systems lose.
Competes with Industrial Hydraulics and Mobile Solutions (Bosch Rexroth) · Power Solutions (Danfoss)
In plain English
Making a crane lift, a tractor steer or a factory arm turn takes force and control. Parker's pumps, motors, cylinders and electronic drives act as a machine's muscles and nerves, changing power into deliberate movement.
Equipment makers pay Parker to fit these pieces into new machines; owners later buy replacements and upgrades through distributors. Engineers help win the original design, which can keep generating parts sales for years. Demand rises and falls with machinery production and factory spending, while the Curtis purchase adds controllers that manage power in electric and mixed-power vehicles.
Aerospace Systems
Aircraft systems produced $7.061B in FY2026 and held $8.498B of Parker's $12.8B order pile. Nearly half of sales came after delivery; watch aircraft build schedules, flying activity and repair demand.
Competes with Flight Controls and Power & Controls (Collins Aerospace, RTX) · Wheels, Brakes and Systems Equipment (Safran)
In plain English
Every aircraft is a web of systems that steer surfaces, move fuel, brake wheels, manage heat, supply power and sense trouble. Parker sells those working parts to commercial and defense aircraft makers, then stays with them for years because flight equipment must remain approved and dependable.
New-aircraft production brings the first sale. Once a plane is flying, airlines and military operators return for replacement parts, repairs and upgrades. It is a long relay race: factory deliveries start the relationship, while upkeep keeps it earning through the aircraft's life.
Commercial aircraft upkeep
Replacement parts, repairs and upgrades for commercial aircraft generated $2.523B in FY2026, up 14.0%. More flying and older fleets bring work; aircraft retirements remove it.
Competes with Aftermarket Solutions (Collins Aerospace, RTX) · Wheel & Brake Services (Safran Landing Systems)
In plain English
The earning starts after the aircraft leaves the factory. Airlines, aircraft owners and repair shops pay for approved replacement pieces, repairs, full rebuilds and upgrades on Parker systems already in service.
Picture a car repair shop where only certain tested parts may go back onto the road, but with far stricter safety checks and aircraft that can stay in service for decades. More flights and older fleets bring more shop visits. Parker's original place on the aircraft makes those later sales harder for an unapproved substitute to take.
Filtration and Engineered Materials
The largest industrial platform made $6.048B in FY2026, up 4.2% but still just below FY2024. Filtration Group closed after year-end and is expected to add about $1.8B during FY2027; watch how cleanly Parker combines it.
Competes with Industrial Air and Process Filtration (Donaldson) · Sealing Technologies (Freudenberg)
In plain English
The unglamorous job is keeping dirt out and pressure in. Parker makes filters for air, gases and liquids, plus seals, coatings, shields and glues that keep machines clean, closed and protected—kitchen strainers and gaskets scaled for factories, engines and sensitive production lines.
Customers buy the first set with their equipment, then return because filter material fills up and seals wear down. Distributors keep replacements nearby, while equipment makers buy directly. The newly purchased Filtration Group deepens that repeat cycle: most of its sales come after the original equipment is already working.
