Hose Assembly Length

For specially made or custom hydraulic hose assemblies, Sinopulse is the place to go. To guarantee appropriate service on the project site, these assemblies will be built with SAE-grade hoses, couplings, and fittings.

Sinopuse Group supplies hydraulic hoses, hydraulic fittings, and hose machines, these are the necessity to build hydraulic assembly, our technical workers have tons of experience to be compatible with your requirements. when you complete the hydraulic hose selection, you can make your custom hydraulic hose assembly by following the steps below.

I.D., O.D., and length are three considerations for hydraulic assembly

To guarantee that hydraulic custom hose assemblies are the proper size, it is essential to consider their ID (inner diameter), OD (outer diameter), and length.

The hose’s inner diameter determines the size of the aperture through which the fluid must pass over a specific amount of time. The hose’s OD may be crucial for several factors, including where it will fit and how strong it is. A particularly powerful high-pressure hose will often have a greater thickness relative to its ID. Naturally, the hydraulic hose length will also play a role in determining what flow rates you can take when combined with your ID. A smaller hose will have a bigger pressure drop or be longer overall than one with a larger diameter.

To transmit fluid through a conduit efficiently, a hose must be appropriately designed to manage the flow with the least amount of pressure loss feasible. Since you want all the energy you put into your prime mover to finally accomplish meaningful work at one of your actuators, whether they are a motor or cylinders, you should aim for the lowest overall pressure drop possible. This is important for efficiency.

The improper hydraulic hose length is frequently specified. A hose that is too short cannot be used at all since it will either not fit or, if stretched too far, will break. It could have too much slack if it’s too lengthy. A hose that is too loose might rub, tear, or move about the machine too much, leading to a catastrophic failure. Additionally, the longer hoses may droop, putting pressure on the crimp and hose contact. Over time, this may lead to wear and leaks.

Also, dangling or drooping hoses may catch on anything or present a trip hazard. You can clamp down a hose to assure safety if it is just a bit too long, like an inch. Measuring the point where the assembly’s fittings meet is what matters most. Not all components’ total lengths are measured from tip to tip.

To identify it, you must know a hose assembly’s length, type, and orientation of the end fittings. So, with no further ado, let us talk about how to measure hydraulic hose length;

How to measure an assembly’s length

The points from which you should measure your hose assembly are explained in the following illustrations of hose assemblies with various combinations of end fittings.

Identification of end fittings

  • Vernier calipers should be used to gauge the OD of the ID or the male thread. Inside the female thread.

NOTE: Threads can deteriorate with time and may not match our tables perfectly.

  • Use a thread pitch gauge to calculate the number of threads per inch or the space between threads in metric connections.
  • To determine the angle of the sealing surface, use the seat angle gauge. The fitting’s centerline and the gauge’s centerline must be parallel.
  • To discover the closest match, compare these three measures together

How to measure the end fittings’ orientation

 The orientation of the end fittings must be specified if your hose assembly comprises elbows (such as 45° or 90°) at both ends. Measure the angle between the fitting closest to you to the fitting further away in an anticlockwise orientation, as shown in the accompanying diagram.

How to order hydraulic assembly

Sinopulse will employ hoses and construction techniques appropriate to the job the hydraulic hose assemblies will be used for while creating a hydraulic hose assembly specifically for your company. Before the sale, we pressure test each assembly using only the best materials. The ends of the hoses are crimped with custom hydraulic fittings without endangering their integrity or creating a weak spot. Your hydraulic hose assemblies will perform to their full potential if they are expertly assembled and constructed from high-quality components.

In that same spirit, Sinopulse can calculate, design, and produce the special hose to your specifications. Often, when you record the specifics, you may have second thoughts, at which point we advise calling a professional. Additionally, you may get in touch with us whenever it’s convenient.

Below are the steps for ordering your custom hose assemblies;

Building and Design

Cold-drawn bar stock is used for the straights while forging and machining are used to create shaped items such as elbows, tees, and crosses.

Most of our connector items are composed of brass and carbon steel, but they may also be manufactured of stainless steel or other materials based on your drawings.

Superior Standards

Being a hydraulic hose manufacturer, we ensure that our design and production procedures are of the highest caliber by upholding the necessary certification and conducting internal inspections.

We follow a mandated rotating gauge calibration plan to ensure that the dimensions of every relevant component are exact and based on the required hydraulic hose length measurement.

We have a skilled crew that performs quality inspections. Rigorous statistical analysis and control are used to regulate the production process by individually trained workers. Each identical fitting component you acquire from us will be guaranteed to meet design requirements.

Shipping and Packaging

All purchases placed with Sinopulse are internally packaged by our staff in sturdy cartons covered with protective caps. All products have text and bar information prominently printed on them. furthermore, custom brands and marks are accepted to imprint on the products.

We usually ship orders days after they are placed. Customers may also ask questions regarding our Just-In-Time manufacturing method or express production and shipment for items that need to be delivered immediately.

Customer care

Additionally, our website will guide you through the numerous metal hydraulic fitting kinds. We can provide you with an estimate in less than 24 hours if you provide us with a sketch of the necessary hydraulic fitting components through email with the requested quantity.


Ordering hydraulic hose is not difficult, determine your hydraulic hose type and say out its trademark based on the SAE 100R series, and then, follow the guideline above, specify the hose I.D., O.D., and hose length, opt for the right fitting, and determine their orientation of the tow ends, and the left tasks can be assigned to us, we can make quality hydraulic hose assembly as your requirements. if you have some questions about that, don’t hesitate to contact us, we are always here to serve you.
