Off-Highway Vehicle
An Off-Highway Vehicle (OHV) is any motor vehicle specifically designed for use on steep or uneven ground. These types of vehicles are easily identified by their large tires, flexible suspensions, or caterpillar tracks. Off-Highway Vehicles fall under one of four categories: Recreational, Construction/Mining, Agriculture, and Industrial.
Parker Fluid System Connectors Division fittings and valves are specifically designed for the construction/mining, agriculture, and industrial off-highway vehicles. Our line of off-highway vehicle fittings and valves are specifically engineered for the rigors of fuel systems, coolant lines, filtration systems, and attachment connections. For off-highway vehicles that utilize air braking systems, Parker offers both push-to-connect and compression style air brake fittings.
Mobile Equipment Product Literature

Diesel Fuel Fittings
Heavy trucks utilize diesel fuel over gasoline for two reasons: (1) Fuel economy and (2) diesel engines provide more torque, which is important for being able to carry heavy loads. Diesel engines work by injecting the diesel fuel into the combustion chamber of the engine and is ignited when the engine piston compresses the diesel fuel. This compression produces high temperatures in the engine compartment. Because of the challenging environment of a diesel engine compartment, diesel fuel fittings need to be heat resistance and leak free. Parker's line of diesel fuel fittings provides years of leak-free dependable service. Our diesel fuel fittings and valves undergo stringent testing to ensure the final product can withstand the high heat and provide a leak free connection.

Engine Coolant Fittings
Glycol-based engine coolants are an essential component to protecting a truck's engine. Without the proper coolant, a truck's engine can start to melt and pre-maturely war down, a costly expense to repair or replace. In addition to preventing engine overheating, engine coolant also provides some lubrication for key components such as the water pump, head gasket, and cylinder and piston timing. Preventing leaks of glycol-based engine coolant is of high importance for protecting employee health and the environment. Accidental ingestion of glycol-based coolants can have adverse effects on an employee's or wildlife's health. Parker's engineering and manufacturing teams have put countless hours into the development and production of our engine coolant fittings. Each fitting is designed and tested to provide years of leak-free dependable service. Our push-to-connect and compression style engine coolant fittings install fast and with minimal tooling. Explore our offering of engine coolant fittings and see which fits your application best.
DOT Air Brake Fittings
Air braking systems are used instead of hydraulic brakes on larger vehicles due to their dependability. An air braking system generates the braking fluid from the atmosphere whereas a hydraulic system is dependent on a reservoir of hydraulic fluid to function properly. The compressed air generated by the air braking system can also be used for other on-vehicle applications such as seat adjusters, air horn, and door controls. Parker's Fluid System Connectors Division manufacturers dependable, easy to install air brake fittings. These fittings are available in both push-to-connect and compression styles.

Reach Stacker
Reach Stackers are a heavy-duty type of forklift, most commonly found in freight terminals or cargo ports. This type of off-highway vehicle moves cargo containers around the terminal or port. Reach stackers are commonly powered by a diesel engine, but in recent years the popularity of alternative fuel / electrified reach stackers has grown in popularity. Parker Hannifin manufactures high-quality products that can be used on both diesel and electrified reach stackers. The Fluid System Connectors Division manufactures ball valves, brass hose barbs, push-to-connect fittings, and compression-style brass fittings for reach stackers.

Mining Loader
Mining loaders are a specific type of loader deigned for underground mining. The main difference between a mining loader and a wheel loader is the height. Mineshafts are roughly 10 feet or less in height, and typical wheel loaders are over 11 feet tall. A mining loader is very compact and low to the ground, averaging only about 5 feet in height. These off-highway vehicles are designed to withstand harsh environments since they will spend their entire useful life underground. Parker Hannifin manufactures high-quality products that can be used on both diesel and electrified mining loaders. The Fluid System Connectors Division manufactures ball valves, brass hose barbs, push-to-connect fittings, and compression-style brass fittings for these off-highway vehicles.

Combine Harvester
The combine harvester is a vital piece of equipment for any farmer. Traditionally, the four steps to a crops harvest (reaping, threshing, gathering, and winnowing) were done by different machines / processes. The combine harvester combined all 4 of these steps into a single process. Combines are available in different sizes and configurations to meet the needs of the farmer. One element all combine harvesters have in common is interchangeable heads. Each crop requires a different head to efficiently harvest the crop, but the downstream processes performed by the combine harvest stay the same. The Fluid System Connectors Division manufactures ball valves, brass hose barbs, push-to-connect fittings, and compression-style brass fittings for these off-highway vehicles. View our product selector to see where these FSC products, as well as other Parker products, are used on combine harvesters.
Wheel Loader
Wheel loaders are the most common and versatile piece of construction equipment. These loaders can be found on construction sites, as well as farms, landfills, and soil processing yards. In addition to a bucket to scoop debris, soil, and other materials, a wheel loader can be outfitted with other implements to customize them to fit the task. Wheel loaders are preferred on my job sites due to the maneuverability that stems form these machines using wheels instead of treads and the articulated body. When looking to rent or purchase a wheel loader, it is important to get the one that fits your needs since these machines are available in different sizes and horsepower. The Fluid System Connectors Division manufactures ball valves, brass hose barbs, push-to-connect fittings, and compression-style brass fittings for these off-highway vehicles.
