Intermediate Bulk Containers (IBCs) are widely used for transporting and storing liquids across various industries, from agriculture to chemical manufacturing. However, ensuring a secure and efficient flow requires selecting the correct IBC tank fitting size. Choosing the wrong size can lead to leaks, inefficiencies, and costly replacements. This guide provides a detailed breakdown of standard IBC fitting sizes, adaptor options, and installation tips to help you make an informed decision.
Standard IBC Tank Fitting Sizes
Most IBCs come with standardised outlet sizes to accommodate different industrial needs. The most common IBC tank fitting sizes include:
- S60x6 (2-inch) Male Buttress Thread – This thread is the industry standard for IBC tanks. It features a 60-mm outer diameter and a 6-mm thread pitch.
- S100x8 (3-inch) Male Buttress Thread – Used in larger IBCs requiring a wider outlet for high-flow applications.
- BSP (British Standard Pipe) Fittings – Compatible with UK plumbing systems, ensuring seamless integration with existing pipelines.
How to Measure Your IBC Fitting Size
- Measure the outlet’s outer diameter using a calliper or tape measure.
- Check the thread pitch (distance between threads) to determine compatibility.
- Refer to manufacturer specifications to confirm the correct size for your application.
Types of IBC Adaptors and Their Uses
IBC tanks can be customised using various adaptors to ensure compatibility with different pipe systems. The most commonly used IBC adaptors include:
- Camlock Adaptors – Allow quick connection and disconnection, commonly used in industrial fluid transfer.
- Hose lock Adaptors – Ideal for garden and water storage applications, connecting IBCs to standard hose fittings.
- BSP Thread Adaptors – Designed for compatibility with UK-standard pipes and fittings.
- Reducers & Expanding Adaptors – Convert outlet sizes to match existing plumbing connections.
- Food-Grade vs. Industrial Adaptors – Stainless steel and polypropylene options for handling sensitive or hazardous liquids.
Choosing the Right IBC Fitting Size
When selecting an IBC tank fitting size, consider the following factors:
- Liquid Type – Chemicals, food-grade liquids, and fuel require different materials and thread types.
- Industry Requirements – Agriculture, chemical storage, and construction all have varying fitting needs.
- Pressure & Flow Rate – High-pressure applications require reinforced adaptors.
- Material Durability – Stainless steel for corrosive liquids, polypropylene for general use.
How to Install & Seal IBC Adaptors Correctly
- Identify your IBC outlet size and choose a compatible adaptor.
- Apply PTFE tape or a rubber washer to create a watertight seal.
- Secure the fitting using a wrench, ensuring a firm connection without over-tightening.
- Test for leaks before full-scale usage.
Common IBC Fitting Issues & Troubleshooting
Leaking Fittings
- Ensure the correct thread type is used.
- Apply additional PTFE tape for better sealing.
Thread Incompatibility
- Use a thread adaptor to match non-standard IBC fittings.
Low Flow Rate
- Check if the outlet valve is fully open.
- Use a larger diameter fitting for higher flow needs.
Sustainability: Reconditioned IBC Fittings
Opting for reconditioned IBCs and fittings is an environmentally friendly choice. Reusing fittings reduces plastic waste and promotes sustainability. Reconditioned fittings are cleaned, tested, and certified for industrial use, making them a cost-effective alternative.
