Air Hose Connectors

Air hose connectors provide tight and reliable seals for attaching high-pressure hoses to air pumps, brakes, and breathing tanks.

Water Hose Connectors

The water or liquid hose is used in both familiar domestic settings like back gardens, as well as a wide variety of commercial and industrial environments, primarily for cooling and cleaning purposes. While a leaking garden hose may not provide too much of a problem, leakage in a factory is potentially dangerous so the connectors used must provide a tight and reliable seal.

Hydraulic Hose Connectors

Hydraulic hose connectors are fittings designed to connect hoses to various components used within hydraulic systems. This could include valves, cylinders, or pumps. Highly secure, hydraulic hose fittings offer tightly-sealed connections, preventing leakage, maintaining a safe operational level of pressure, and directing the flow of hydraulic fluid within the system.

Brass Hose Connectors

Brass hose connectors make a good choice for low-pressure hosing and are often used with domestic garden watering equipment as well as fuel lines. Brass is resistant to corrosion and pliable but strong. However, it is important to ensure that only quality brass has been used in the manufacturing process as cheaply-made brass can be weak and porous.

Aluminium Hose Connectors

Aluminium is a notably light metal – only around two-thirds the weight of steel or brass with the same mass. This makes it a great choice for larger connectors used within industrial settings. It is also highly resistant to corrosion, pliable, and less expensive than steel alternatives.

Steel Hose Connectors

Carbon steel is a blend of steel and carbon. When properly treated, carbon steel is stronger than the regular alternative, although less pliable. Varying the blend of carbon and steel provides different strengths and levels of resistance to corrosion. Hose connectors made from carbon steel are widely used within industrial environments because they can withstand high pressures.

Stainless Steel Hose Connectors

Stainless steel is an alloy of steel and chromium, highly resistant to rust and other corrosive agents such as saltwater and spray. It is also suitable for use with very high-pressure liquids. Its principal disadvantage is the price – stainless steel hose connectors can cost several times as much as those made from regular carbon steel.

Plastic Hose Connectors

Some domestic hose connectors are made from a type of plastic called polyamide. It is inexpensive, highly versatile, and perfectly adequate for low-pressure domestic use.

What are Hose Connectors Made of?

Hose connectors are available in a variety of materials including stainless steel, standard or carbon steel, brass, aluminium, and polyamide (plastic).

What Size is a Standard Hose Fitting?

There is no standard size because there is no singular standard use for hose connectors. They are connected to different-sized devices for varying tasks, in many environments. You should start by considering the specifics of the task at hand then select the right size connector.

How Do Hose Connectors Work?

Hose connectors work by creating a water or airtight seal, normally via a carefully-calibrated combination of threading and metal tubing.

How Do You Fit a Hose Connector?

In most cases, the process is a straightforward one:

• Ensure that the end of the hose to be attached is neatly cut
• Unscrew the sealing cap from the connector and pass this over the end of the hose
• Firmly screw or slide the connector onto the hose
• Slide the sealing cap back up the hose and onto the cap, screwing it back into place. This will push the spokes around the end of the connector into the hose, creating a firm connection
• Connect your tap, hose, nozzle, or other attachment to the connector and use

Can You Connect Two Hoses Together?

Yes, this is a routine function of a hose connector. They can be connected to provide additional length, alter the direction of liquid flow, and repair breaks. Simply ensure that the connectors fitted to each end of the hoses are compatible with each other (e.g. female to male).

Do You Need a Hose Connector?

Yes. Without a solid seal created by a hose connector, it would be impossible to connect one liquid or air-bearing device to another without significant and potentially highly hazardous leakage.

Are All Hose Connectors the Same?

No, they come in a variety of designs and sizes for different tasks. For example, there are male and female connectors, terms that refer to the way they attach to other hoses or connectors. Other designs include nozzles, valves, varying pressure tolerances, and adapters for use in a multitude of specific circumstances.
