Things to Consider Before Buying Hydraulic Pressure Test Kits

Judging from the top products mentioned above, there are quite a lot of things to consider when searching for hydraulic pressure test kits.

For newbies, this can sound daunting, especially because you are not familiar with the language and slight technical jargon involved.

Due to this, it is prudent to outline how hydraulic pressure testing kits work. You’ll find the answer in the FAQs below, after the points to consider before buying a testing kit are discussed.

Factors to Consider

As mentioned, settling on the best hydraulic pressure test kit can be challenging. Whereas you may have some instinctive sense regarding how much size and power you may need for your vacuum cleaner, you may not be familiar with hydraulic pressure testing tools.

Therefore, consider the following as you go shopping for one.

Intended Use

Think the extent you will be needing the kit. This will help you in making the decision on the right hydraulic pressure test kit from the three common classifications: professional, light-commercial, and residential. It also applies in choosing other types of kits, like these top-rated tone and probe tracing kits.

Type of Pressure Gauge

Nearly all hydraulic pressure gauges measure up to 10,000PSI, even if the maximum known hydraulic pressure ranges between 3,000 to 5,000PSI. That said, regardless of whether you will use it to operate machinery or test equipment, finding the right pressure gauge helps lessen the common downtime.

If you intend to use the kit for hydraulic systems, find specifically designed gauges for hydraulic uses. Additionally, note the common problems of gauge reliability such as pulsation, vibration, and pressure spikes.

To avert this, consider gauges with a liquid-filled case that protects it from extreme vibration and pressure cycles. The gauge can also have a restrictor that impairs any potential damage to the gauge. Similarly, the forged brass case prevents resonant frequencies from damaging internal parts.

Kit Gauge Fillers

Gauge fillers resolve the common problems associated with gauge reliability. However, note that the viscosity of these liquid fillers plays an important role in the proper functioning of your gauge.

The higher the viscosity of the liquid, the more resistant it will be to problems caused by vibrations. Therefore, when selecting between glycerin-filled, water-filled, or dry filler, check the variations on pressure, temperature range, needle response time, and the anticipated vibration.

Pump Flow

Importantly, you should consider the pump flow of the test kit and compare it to the rated output. The pump flow of the kit should be high enough to meet and surpass your repair, maintenance, and reporting needs.

Other features to consider

• Relieve valve – hydraulic pressure testing kits usually have multiple relieve valves. Ensure that you test the conducting pressure of each valve to confirm that they are working effectively before buying a kit.
• Cost – hydraulic pressure test kits come in varying price quotations. This is solely dependent on the product features and the brand. This shouldn’t be a deal-breaker. Always begin by evaluating the product features before checking the price.
• Warranty – all workshop products should be sold at reasonable warranty periods. This will provide a window for compensation in case your product doesn’t function as expected. Most of these products come with a warranty period ranging from one year to five years. This provides a guarantee that manufacturers stand behind the quality and functionality of their products.
