The Most Important Parameters for the Process of Hydraulic Tees

For the correct realization of the parts through the hydroforming process, some production and material aspects are important:

● Formability of the material: It is necessary for the process to work properly and the piece, for example the tee, does not break during the application of pressure.

● Friction at the interface: The friction between the mold and the piece must be properly calibrated.

● Machine parameters: These include times, pressures and movements of the axial cylinders that must be set correctly for the effective and efficient production of the parts.
This innovative forming technology represents a concrete possibility for the present but also a fundamental prospect for the future in order to meet the needs and limitations of modern industry.

Selection Criteria for Hydraulic Tees

Cosider the following criteria before selecting the hydraulic tee types for your application:

Size: The internal and external diameter of the fittings are two important sizes to consider. These diameters of the fitting should be compatible with the hose diameter. Over or under-sized fittings can cause leakage or the connection to fail.

Material: The material of the hydraulic fitting should be compatible with the hydraulic fluid and with the operating environment. The most commonly used fitting materials are brass, aluminum, steel, or stainless steel.

Temperature: The hydraulic fittings should be suitable for your temperature range.

Pressure: The hydraulic fittings must be suitable for your pressure range, including the pressure spikes. Operating beyond this range can cause damage to the fittings.

Application: The type of application also determines the fitting type to be used. Tee or cross fittings are used for mixing or distribution application.

Assembly: If the hydraulic system requires frequent connecting and disconnecting of the hose or tube, the hydraulic quick-connect fittings can be used. Similarly, hydraulic compression fittings can be used to remove the need for welding or soldering of the fitting. It uses a compression nut to tighten against the ferrule creating a very tight seal. It can be used in areas with high temperatures as welded joints can leak in such environments.

What Are Hydraulic Tees Made Of

Hydraulic tees are typically fabricated from strong, durable materials capable of withstanding high-pressure environments.
Commonly, they are made of materials like steel and stainless steel offering specific benefits such as corrosion resistance, heat tolerance, or light-weight properties.

Steel hydraulic tees

Steel hydraulic tees are highly valued for their superior strength, durability and resistance to high pressures and temperatures. Often utilized in industrial settings, they are resilient against harsh environments, but may be prone to corrosion if not properly maintained or protected.

Stainless steel hydraulic tees

Stainless steel hydraulic tees are renowned for their exceptional corrosion resistance and strength. These hydraulic tees are often employed in applications where the hydraulic system is exposed to corrosive substances, or high levels of cleanliness are required.

Precautions for Tightening Hydraulic Tees

Use the correct fittings. Plain ol' tapered (NPT) hydraulic tees are designed for low-pressure fluids of 300 psi or less. They are not designed for, nor safe, when installed in high-pressure hydraulic situations. Tapered fuel (NPTF) hydraulic connectors are physically similar to NPT fittings, but are plated with zinc dichromate, which gives them a silver or gold tint. Hydraulic tees are safe for use in high-pressure applications. If you don't know for certain if a fitting is NPT or NPTF, don't use it in a high-pressure hydraulic application.

● When installing an hydraulic tee in a high-pressure situation, don't tighten the fitting then back it off to align it with a hose, line or other fitting. Because of the unique design of NPTF threads, those fittings should be tightened into alignment, and never loosened.

● Straight-thread O-ring fittings are the ones you thread into place, then tighten a nut on the fitting against an O-ring built into the fitting. Fyi, to 'test' an old, used straight-thread o-ring fitting, shake the fitting. If the washer slides back and forth on the fitting and clicks, it's worn out. To correctly install a straight-thread o-ring fitting, twist the retaining nut away from the washer and o-ring then install the threaded portion of the fitting until it is hand-tight. You can can "back-off" this sort of fitting from hand-tight up to one revolution to align it with other plumbing. Once aligned, tighten the nut until it is "firm" against the washer and o-ring, with the nut becoming snug with a feel of metal-on-metal in less than one revolution. Over-tightening causes as many leaks as under-tightening.

● Flared hydraulic tees come in 37- and 45-degree designs and may share similar thread pitches. This means a 45-degree male fitting may thread into a 37-degree female, but they won't seal correctly. Beyond making certain the cone-angles of fittings match, don't over-tighten flared fittings. Over-tightened flared fittings leak as badly as under-tightened fittings because the immense torque of over-tightened threads cracks or distorts the precision-machined flared portions of the fittings.

Uses of Hydraulic Tees
