Hydraulic tube and hose clamps secure pressurized lines against vibration, surge spikes, and chafe so a hydraulic system routes cleanly without leaks or fatigue cracks at the fittings. The right clamp is defined by the line outside diameter it grips, the clamp body material and series, and how it mounts to the machine frame or weld plate. Matching an obsolete or unmarked clamp by tube OD and series? send your specs for a cross-reference.

How to Choose a Hydraulic Tube or Hose Clamp

A clamp is sized to the line it carries and to the working pressure of the circuit. Confirm these before ordering:

Line outside diameter: measure the tube or hose OD, not the bore. Clamp bodies are cut to a specific OD or grouped by tube series, and an oversized half-shell will let the line walk under vibration.
Clamp series and group size: most stackable clamps follow a standard group sizing where one rail mounts multiple lines; match the series so weld plates and cover plates interchange.
Body material: polypropylene or polyamide for general routing, aluminum or steel for high-temperature, high-vibration, or heavy-line runs. Verify material against your fluid temperature and ambient conditions.
Working pressure of the line: the clamp should match or exceed the rated pressure class of the tube or hose it restrains, since surge and pressure spikes drive the reaction load into the clamp.
Mount and reaction hardware: confirm weld plate, cover plate, and bolt thread so the clamp anchors solidly and the reaction load transfers to the frame, not the fitting.

Which Clamp Is Right for the Job?

Single clamps hold one line and suit short, isolated runs; stackable clamps share a rail and twin bolts to bundle several lines along a common path, which keeps a manifold or pump feed tidy and serviceable. Polymer-body clamps damp vibration and resist corrosion on most routing; metal-body clamps take higher temperatures and heavier lines near a pump or motor. If a clamp on the machine is unmarked, confirm fit by measuring the line OD with calipers and counting the lines per rail, then match the series and group size before you order.

Complete the System

Clamps are the last step in a clean routing job, so build the run around the components they secure. Pair them with Hydraulic Hoses sized to the same OD, and anchor the lines feeding your Hydraulic Pumps and Hydraulic Motors where vibration is highest. Lines running to Hydraulic Cylinders benefit from clamping near direction changes to control whip, and Pneumatic Quick Couplers on auxiliary lines stay aligned when the run upstream is clamped square.

Cross-Referencing an Obsolete Clamp

Many machines run clamp series that the original maker has discontinued or rebranded, and a missing half-shell can idle a line that is otherwise sound. A hydraulics distributor since 1963, Northern Hydraulics can match a clamp by tube OD, series, group size, and mount style rather than by a part number that may no longer exist. Measure the line, note how many lines share the rail, and request a cross-reference.

Clamps – Frequently Asked Questions

How do I measure for the right hydraulic clamp size?

Measure the outside diameter of the tube or hose with calipers, not the inside bore. Clamp half-shells are cut to a specific OD or grouped by tube series, so the OD measurement determines which clamp body grips the line securely without letting it walk.

What pressure should a hydraulic tube clamp be rated for?

The clamp should match or exceed the rated pressure class of the line it restrains, because surge and pressure spikes drive the reaction load into the clamp body and mount. Confirm the working pressure of your tube or hose, then choose a clamp series and material suited to that class.

What is the difference between single and stackable clamps?

A single clamp holds one line and suits short, isolated runs. A stackable clamp shares a rail and twin bolts to bundle several lines along a common path, which keeps feeds to a manifold, pump, or motor tidy and easier to service. Match the series so weld plates and cover plates interchange.

Should I use a polymer or metal clamp body?

Polypropylene or polyamide bodies damp vibration and resist corrosion on most general routing. Aluminum or steel bodies take higher temperatures and heavier lines, which makes them a better fit near a pump or motor where heat and vibration are highest. Verify the material against your fluid temperature and ambient conditions.

Where should I clamp hydraulic hose runs?

Anchor lines where vibration is highest, such as feeds to Hydraulic Pumps and Hydraulic Motors, and add a clamp near direction changes on lines running to Hydraulic Cylinders to control whip. The goal is to transfer load into the frame rather than the fittings.

Do clamp weld plates and cover plates interchange between brands?

They interchange when the clamp series and group size match. Standard stackable clamp systems share group sizing, so a weld plate and cover plate from one supplier often fit another within the same series. Confirm the series and group size before mixing components.

Do hydraulic clamps ship the same day?

In-stock hydraulic tube and hose clamps ship the same day from Great Falls, MT when ordered before the daily cutoff. Stock status is shown on each product, and orders placed after the cutoff ship the next business day.

Can you cross-reference an obsolete or unmarked clamp?

Yes. We match clamps by tube OD, series, group size, and mount style rather than by a part number that may be discontinued or unreadable. Measure the line, note how many lines share the rail, and request a quote.
