Part number 1505418 is a clutch master cylinder designed specifically for the Ford Transit. Its side-mounted hydraulic port effectively resolves common installation issues; the hydraulic line connects along a natural path without requiring forced bending or placing undue stress on the fitting. This results in a clean, streamlined connection, smooth fluid flow, and a more logical installation angle.
This feature is highly practical for purchasers and repair shops alike: choosing the wrong port orientation can make installation difficult—forcing the hydraulic line to either fall short or undergo sharp bending to connect—and creates a risk of leaks at the fitting. Selecting the correct port orientation is crucial, as it directly determines whether the installation goes smoothly or leads to problems once the vehicle is on the road.

Application
This unit fits the Ford Transit across three body configurations. These are not model-year-specific variants — the Transit name here refers to a generation that covered a broad production window, and all three body types share the same lateral-port clutch hydraulic specification.
The Transit Box is the standard panel van configuration — the highest-volume variant in the Transit range and the most commonly seen in aftermarket workshop demand. These vehicles are the workhorses of courier networks, trade businesses, and light commercial logistics across Europe and export markets. High daily mileage and frequent clutch operation make them consistent consumers of clutch hydraulic components.
The Transit Bus covers minibus and people-carrier configurations used in private hire, school and community transport, hotel and airport transfers, and tour operations. Bus-bodied Transits typically carry higher passenger loads than vans, which affects braking and clutch system loading. They also tend to be retained in service longer than van variants because their total mileage accumulates more slowly, meaning they pass through the clutch master cylinder replacement window later but still reliably.
The Transit Platform and Chassis covers the bare cab-and-chassis units used as the foundation for specialist conversions — tippers, flatbeds, recovery vehicles, refrigerated bodies, welfare units, and ambulance builds. These vehicles operate in the most demanding conditions of any Transit variant. Construction sites, waste collection routes, off-road access tracks — the clutch system absorbs more abuse per kilometre than in any standard road-going application. Getting the correct hydraulic spec on these vehicles matters because the consequences of a misfit or early failure are felt in vehicle downtime rather than just inconvenience.
Manual transmission variants only across all three body types. Always verify gearbox configuration before applying this SKU to a vehicle record.

Procurement Motivation
Building a Private Label Range Around Specification Accuracy
The lateral port distinction is exactly the kind of product detail that separates a well-built aftermarket catalog from a generic one. Most distributors list Transit clutch cylinders without specifying port orientation — which means their customers receive the wrong unit and return it. A private label brand that catalogs this correctly, leads with the lateral port specification in its product description, and documents the OE cross-reference list accurately will consistently outperform generic alternatives in search results and in workshop buyer preference. The 12 OE reference numbers attached to this part provide strong indexing across TecDoc and regional catalog systems. Transit Box and Platform/Chassis applications attract a commercial buyer profile — fleet parts departments, workshop groups, and specialist commercial vehicle distributors — who tend to place larger and more regular orders than passenger car parts buyers.

Bulk Supply for Commercial Vehicle Distribution Networks
The Transit generation covered by this part sits in the age bracket where consistent replacement demand is established and predictable. Fleet operators managing aging Transit vans and chassis units need reliable supply on clutch hydraulic components, and the buying pattern is driven by mileage accumulation rather than model year. Distributors supplying independent commercial vehicle workshops, van hire fleets, and minibus operators across the UK, continental Europe, the Middle East, and Africa need availability on this SKU year-round. The three body type coverage — Box, Bus, Platform — means a single cataloged line serves the full Transit commercial range for this specification.
