Different Types of Industrial Hose Fittings Explained

In almost every industrial environment, hoses play a crucial role in transporting air, water, chemicals, fuels and hydraulic fluids safely and efficiently. But a hose is only as reliable as the fitting that connects it.

Choosing the right connector prevents leaks, protects equipment and ensures systems operate smoothly. In this guide, we’ll break down the different types of hose fittings, explain where each one is used and outline what to consider when choosing hose couplings for your application.

What Are Industrial Hose Fittings? 

Industrial hose fittings, also known as hose connectors or couplings, are components that attach a hose to another hose, a pipe or a piece of equipment. They ensure a secure, leak-free connection that withstands the specific pressures, temperatures and media used in your operation. 

Because industries vary so widely, there are many industrial connector types, each designed for a specific performance requirement such as fast release, high pressure, corrosion resistance or chemical compatibility. 

Key Factors to Consider When Choosing Hose Couplings 

Before selecting a hose fitting, consider the following: 

#1: Material Compatibility

Different materials suit different environments: 

• Stainless steel: ideal for corrosive, chemical or hygienic applications
• Brass: common for air and water, offering good strength and corrosion resistance. 
• Aluminium: lightweight and suitable for general-purpose use.
• Polypropylene/plastics: chemical-resistant, cost effective options for low-pressure systems. 

#2: Pressure and Temperature Ratings 

Hydraulic and high-pressure applications require fittings built to withstand extreme conditions, whereas low-pressure water or suction hoses require less robust couplings. 

#3: Hose Diameter and Thread Type

Incorrect thread type, such as mixing BSP with NPT, can lead to leaks or failure. Always match connections precisely. 

#4: Operating Environment 

Exposure to chemicals, saltwater, abrasive materials or outdoor conditions can influence the ideal fitting material. 

#5: Industry and Application

Food-grade applications differ from heavy construction, and industrial chemicals require connectors resistant to corrosion and permeation. 

Main Types of Industrial Hose Fittings 

Below are the most widely used types of hose fittings across industries such as chemical processing, manufacturing, construction, agriculture and marine. 

Camlock (Cam and Groove) Fittings 

One of the most popular coupling types in the industry, camlock fittings allow fast, tool-free connection. 

Best for: 

• Chemicals
• Petroleum products
• Water and wastewater
• Powder and granular materials 

Benefits: 

• Quick and easy to connect/disconnect
• Strong, secure seal
• Available in aluminium, stainless steel, brass and polypropylene 

Threaded Fittings 

Threaded fittings rely on male and female threads to create a tight seal. 

BSP (British Standard Pipe) and NPT (National Pipe Thread) are the two main thread standards. BSP is commonly used in the UK and Europe, while NPT is preferred in North America. 

Best for: 

• Air lines
• Water systems
• Hydraulic and pneumatic setups 

Benefits: 

• Widely compatible
• Reliable long-term seal
• Available in numerous materials and configurations

Hydraulic Hose Fittings 

Hydraulic systems operate under extremely high pressures, so fittings must be crimped or swaged professionally to guarantee safety. 

Types include: 

• Crimped hydraulic fittings
• Reusable field-attachable fittings
• JIC, ORFS, BSP and metric hydraulic connectors

Best for: 

• Construction machinery
• Manufacturing equipment
• Industrial hydraulic systems 

Quick-Release Couplings 

Designed for speed and efficiency, quick-release fittings allow frequent connection and disconnection without tools. 

Best for: 

• Air tools
• Water lines
• Testing equipment
• Pneumatic systems 

Benefits:

• Reduces downtime
• Simple one-handed operation 

Flanged Hose Fittings 

Flanges are bolted connections ideal for larger diameters or high-pressure applications. 

Types include:

• ANSI
• DIN
• PN-rated flanges 

Best for:

• Industrial pipelines
• Marine systems
• Oil and gas applications

Bauer Couplings 

Bauer-style fittings are rigged, galvanised connectors commonly used for suction and delivery hoses. 

Best for:

• Agriculture
• Construction sites
• Water pumping
• Slurry and irrigation systems 

Benefits: 

• Quick to assemble
• Self-aligning design
• Excellent for uneven ground 

Storz Couplings 

Storz couplings feature a non threaded "twist-lock" connection originally designed for firefighting. 

Best for: 

• Fire hoses
• Wastewater handling
• Emergency services 

Benefits:

• Connects quickly under pressure
• Works even when hoses are dirty 

Materials Used for Industrial Hose Connectors 

Choosing the right material is just as important as choosing the fitting style. Here’s a quick guide: 

Matching the Right Fitting to Your Application 

The correct connector depends on the environment, media and performance needs of your specific industry.

• Chemical processing: stainless steel or polypropylene camlocks
• Food and beverage: hygienic stainless fittings
• Construction: bauer couplings and hydraulic fittings
• Marine: stainless steel flanges and corrosion-resistant connectors
• Manufacturing: pneumatic quick-release hydraulic couplings 

When in doubt, it’s essential to consult a specialist to ensure safety, compliance and long-term performance. 

Safety Considerations When Selecting Hose Fittings 

Safety should always be a priority. Keep in mind: 

• Never mix incompatible thread types
• Ensure fittings match the hose’s pressure ratings
• Inspect regularly for wear, corrosion or deformation
• Replace damaged fittings immediately
• Use only manufacturer-approved hose clamps or crimping methods

A properly matched and maintained hose system significantly reduces the risk of blow-offs, leaks and equipment failure. 

Why Choosing the Right Hose Fitting Matters 

The correct hose coupling can: 

• Improve system performance
• Reduce downtime
• Extend hose life
• Protect operators and equipment
• Prevent costly leaks or contamination

A small component can make a big difference.
