Quick guide: hydraulics & pneumatics protection in specialist vehicles

Agricultural vehicle

Construction, agricultural and mining vehicles spend more time on sites than on the road. For all three; demand for reliable operations, reduced downtime and low maintenance costs mean build quality is critical.

These vehicles need to be durable and perform in the most demanding environments, whilst meeting safety and environmental regulations. Pneumatics and hydraulics play a critical role in the operation of these machines and their importance is not to be underplayed. Original Equipment Manufacturers (OEMs) need value in their components – quality, competitive pricing and fast response to get the vehicles to market.

We’ve put together this guide to help design engineers, OEMs and hydraulic designers to choose the small components they’ll need. Most of our recommendations can be used across construction, agricultural and mining vehicles. The hose protection you need for concrete mixer truck hydraulic systems or pneumatic mining drills and mining vehicles can also be used for tractor hydraulic hoses.

Construction and mining vehicles

Construction and mining vehicles

Downtime due to failed vehicle parts will not only add to the user’s operating costs but damage your reputation. To help ensure high performance, you’ll need to consider protection for your pneumatic and hydraulic design. Our quality components are durable and available in materials that stand up to the rigorous demands of off-highway vehicles and their systems. Just some examples include:

Bulldozers and hydraulic bulldozer systems: typically used for shallow digging and ditching; transportation of material in short distances; spreading soil dumped from trucks; rough grading; and removing stumps and boulders.

Concrete mixer trucks and concrete mixer truck hydraulic systems: combines cement, aggregate and water to form concrete. The hydraulic system transforms the engine power to hydraulic power, supplying power to the mixer drum rotation.

Backhoes and backhoe hydraulic systems: backhoe loaders use hydraulics, usually oil, to transmit force from one point to another.

Hydraulic truck conveyor: mounts easily to road graders, loaders and tractors to widen roads, install pipe bedding and fill trenches, just to name some of its capabilities. The unit for efficient delivery of both free-flowing and large chunky materials.

Pneumatic conveyor: moves bulk materials by means of air through pipelines. Commonly used in the mining industry.

Here are the components you’ll need for your construction or mining applications:

​Spiralguard® hose protectors

Spiralguard® hose protectors

Tough, durable Spiralguard protects hydraulic and pneumatic hose assemblies in applications ranging from hydraulic arms, pneumatic brake lines and dump-truck tray bed lifts to forklift hydraulic hoses, a hydraulic hale bay handler and tractor hydraulic hoses. Excellent recovery memory to maximize hose coverage and exceptional anti-crushing performance to reduce downtime. Maintains a high-abrasion resistance and proven in harsh conditions. Good resistance to UV rays. Suitable for wrapping single hoses or multiple hose bundles. HDPE. Flame-retardant and anti-static mining safety-approved Spiralguard® also available.

​Hose protection sleeves – textile, mining safety approved

Hose protection sleeves – textile, mining safety approved

Mining-safety-approved hose protection sleeves are robust, but lightweight for optimum UV burst diffusion. This hydraulic hose burst-diffusion wrap safeguards against pin hole punctures by diffusing the fluid or air in backhoe hydraulic hoses and front-end loader hydraulic cylinders. Meets ISO 6945 abrasion standard, Fed-STD-191 test method 5309 and ASTM D6770. Nylon 6/6.

​T-Bolt hose clamps

T-Bolt hose clamps

Hydraulic hose clamps and pneumatic hose clamps, sized to SAE standards and designed to provide a dependable seal on larger diameter hoses where high vibration occurs, such as in excavator hydraulic hose and pneumatic trench shoring equipment. 301 stainless steel.

Also available: worm-drive hose clamps in carbon steel or stainless steel.

​Hose wear protectors

Hose wear protectors

Protects hoses against point-of-contact wear with abrasive surfaces. Typically used on hydraulic hoses, fuel or oil lines, brake systems, wiring harnesses and battery cables. Hose protectors are easy to assemble or remove. Molded grooves are designed to fit with cable ties. Made of durable PVC.

Construction and mining vehicles
​Threaded sealing caps – UNF threads

Threaded sealing caps – UNF threads

Resists solvents and potential shearing. Includes an internal neoprene rubber sealing disk for the cap to limit fluid leakage and entry of particles, protecting dump trucks and hydraulic front loaders. Hand tightening is recommended.

​Cable ties – locking, weather resistant

Cable ties – locking, weather resistant

Durable weather-resistant cable ties have all of the same benefits as our standard ties plus UV-resistance for outdoor use. Ideal as one of your bulldozer components, backhoe brake parts or any other ground-engaging tools (GET). UL94 V-2, nylon 6/6. See our complete range of cable ties, from heat-stabilized cable ties to 316 stainless-steel cable ties.



Ideal for your hydraulic boom crane designs or as one of your hydraulic compactor parts. Protects cables, wires, tubing and hoses. Installs instantly by simply snapping into holes. Excellent adhesion and designed to fit standard sheet metal holes. Available in TPR, PVC and EPDM.

Steel p-clamp with rubber cushion

Steel p-clamp with rubber cushion

P-clamps for cables are also ideal for clamping pipes, hoses and wires. The rubber cushion provides some protection for the hose while the steel component and screw mount application result in a secure fastening. Operating temperature range: -76˚F to 203˚F.

Tapered caps and plugs

Tapered caps and plugs


Designed for each part to cap multiple O.D.s or plug multiple I.D.s. Tapered plugs and caps are made of LDPE material to protect against damage, dirt, moisture and corrosion during storage and shipping.

Agricultural vehicles


Crops, livestock and forestry vehicles are often multi-purpose, used with many different attachments and subject to increasingly harsh environments, so quality is key.

If your vehicle has a hydraulic system design, hydraulic circuit design will play a part. You’ll need to evenly distribute hydraulic flow to all subcircuits, yet you’ll also have to maintain the ability to bring that hydraulic power to work on motor functions for fast travel. Energy efficiency, easy operation and maintenance and reliability should be your first concerns for the vehicles and systems you’re designing and manufacturing, such as:

Farm tractor hydraulic systems: All tractors rely on hydraulic control systems that use hydraulic oil to raise and lower parts, provide power to motors and other devices.

Combine harvester hydraulic system: The combine harvester’s very name comes from the machine’s ability to carry out multi-functions. The pumps and motors operate various functions. The first pump and motor might operate at least a crop-cutting knife, while the second pump and motor can be used to operate at least one conveyor. Both pumps and motors work within hydraulic circuits. They share hydraulic fluid with machine's hydraulic fluid reservoir. In turn, this reduces system weight and maintenance requirements while making the machine easier to operate.


Hydraulic hay bale handler: The hydraulic system monitors the pressure on belts exerted by hay. When signalled that a predetermined tension is reached, the tractor operator stops and the bale is wrapped. The hydraulic cylinders then open the rear of the baler and the bale is dropped.

Here are the high-quality components you’ll need for agricultural applications:

​Hydraulic quick-release caps and plugs
