SAE 100R4 Hydraulic Oil Suction and Return Hose Introduction

 
Hydraulic suction hoses, also commonly known as hydraulic return line hoses, are primarily used for the suction and return lines of hydraulic systems. Unlike ordinary high-pressure hoses, their key feature is an internal spiral steel wire reinforcement layer that withstands vacuum or negative pressure, preventing the hose from collapsing due to external atmospheric pressure during the suction process, thereby ensuring smooth fluid flow into the hydraulic pump.
 
SAE 100R4 hydraulic suction and return hose complies with SAE J517 standards and is specially used for the oil suction and return lines of hydraulic systems. It is oil-resistant, pressure-resistant, and bending-resistant.
 

SAE 100 R4 hydraulic suction hose features

Our hydraulic suction hoses feature a three-layer construction, with both inner and outer layers made of high-quality synthetic rubber. The inner tube is oil-resistant and corrosion-resistant, making it suitable for conveying a variety of fluids, including petroleum and water-based hydraulic oils. The outer layer is abrasion-resistant, weather-resistant, and UV-resistant, protecting the inner tube from environmental damage and extending the hose's service life.

Hydraulic hoses range from 3/4" to 4" in diameter. Each hose is reinforced with spiral steel wire, allowing even large diameters to withstand four times the burst pressure.

 

The maximum working pressure reaches 2.1 MPa/305 PSI with a 3/4" inner diameter.

 

As the hose's inner diameter increases, the working pressure it can withstand decreases. For a 4" inner diameter hose, the maximum working pressure reaches 58 PSI.

FAQs About SAE 100R4 Suction Hose

 

Q1: What is SAE 100r4?

A1: SAE 100 R4 is mainly used for oil suction and delivery in hydraulic systems. It has a three-layer structure. The inner layer is oil-resistant synthetic rubber, the outer layer is wear-resistant and weather-resistant rubber, and the middle layer is a textile reinforcement with spiral steel wire reinforcement. It can withstand vacuum or negative pressure. It is more pressure-resistant than ordinary textile-reinforced hydraulic hoses and has a wide range of uses.

 

Q2: Can SAE 100R4 be used for high-pressure hydraulic lines?

A2: No, it is designed for suction and return applications, not for high-pressure working lines.

 

Q3: What fluids are compatible with SAE 100R4 hose?
A3: Petroleum-based hydraulic fluids, water-glycol, and some synthetic fluids (check chemical compatibility).

 

Q4: What is the temperature range of SAE 100R4 hose?
A4: Typically -40°C to +100°C (-40°F to +212°F).

 

Q5: What sizes are available?

A5: From 3/4" to 4", with custom options available.

 

Q6: What is the difference between SAE 100R4 and SAE 100R3?
A6: SAE 100R4 is designed for suction and return lines, with reinforcement that can handle vacuum, often with spiral steel wire reinforcement, while SAE 100R3 is a low-pressure hydraulic hose with textile braid reinforcement.

Comprehensive Guide to Safe and Effective Brake Hose Replacement Procedures
Maintaining your vehicle’s braking system is crucial for safety, and a key component of this system is the brake hose. Over time, brake hoses can deteriorate due to age, exposure to the elements, and constant pressure. This guide provides a comprehensive overview of brake hose replacement, covering everything from identifying when replacement is necessary to the process itself. Ignoring worn brake hoses can lead to brake failure, so understanding the signs and knowing how to address them is vital. Hydraulic Hose Plus offers a wide selection of high-quality brake hoses to ensure your vehicle’s safety. Brake hoses are responsible for carrying brake fluid under high pressure to the brake calipers at each wheel. As they age, the rubber can become brittle, crack, or swell. This compromises their structural integrity and can lead to leaks, reduced braking efficiency, or even complete brake failure. Regular inspection and timely replacement of brake hoses are essential safety measures. Signs of deterioration include visible cracks, blisters, bulges, or leaks, as well as a spongy brake pedal feel. Delaying brake hose replacement can significantly increase stopping distances and put you and others at risk.

Comprehensive Guide to Silicone Auto Hoses for Enhanced Vehicle Performance
In the world of automotive performance and reliability, the often-overlooked component of the engine cooling and intake systems – the auto hose – plays a critical role. Traditional rubber hoses are prone to degradation from heat, oil, and pressure. This is where silicone auto hoses come into play, offering a superior alternative. This article delves into the benefits, applications, and considerations for choosing silicone hoses, providing a detailed overview for automotive enthusiasts, mechanics, and anyone looking to enhance their vehicle's performance. Ensuring your cooling and intake systems are equipped with quality hoses is crucial for preventing costly engine damage and maintaining optimal vehicle operation. Compared to traditional rubber hoses, silicone auto hoses offer a multitude of benefits. They exhibit exceptional resistance to high temperatures, often withstanding temperatures up to 500°F (260°C) without degradation. This is particularly important in modern engines that generate significant heat. Silicone also doesn’t swell or crack when exposed to oil, coolant, or other automotive fluids. This durability translates to a longer lifespan, reducing the frequency of replacements and saving you money in the long run.
