IBC Adapter S100x8 Female Butress to 2"BSP Female
Step a 3 Inch DN80 Valve Down to 2 Inch BSP

What This Product Is
A PP adapter with an S100x8 3 inch female buttress inlet and a 2 inch BSP female outlet, sealed with a PE gasket. It is made for DN80 IBC valves and brings the large outlet onto a standard 2 inch BSP thread so pipework and equipment can be connected.
Key Benefits
- Bridges S100x8 to 2 inch BSP in one part, so there is one joint to check
- Keeps a 2 inch bore, which is the practical limit of most transfer pipework
- The PE gasket seals against the valve face without tape
- Fits most DN80 IBC valves rather than a single brand
What Goes Wrong Without It
- A 3 inch buttress valve has no direct route into 2 inch BSP pipework
- Large valves are often left uncoupled and the tote is drained through the small top opening instead
- Improvised reductions on a DN80 outlet leak under the head of a full tote
Application Scenarios
- Process plants drawing from DN80 IBC valves into fixed pipework
- Bulk chemical handlers transferring at full bore between tote and tank
- Reconditioners converting returned totes to a house standard

How to Specify and Use It
Confirm the valve outlet is S100x8, the 3 inch buttress size
Hand tighten the adapter onto the valve with the PE gasket in place
Screw a 2 inch BSP male fitting into the outlet
Support the pipework independently so the valve does not carry its weight
Comparison With Other Products
Where an S60x6 to BSP fitting works on the more common 2 inch valve, this adapter is the equivalent part for the larger 3 inch DN80 valve. For a plain drain path rather than a pipework connection, the S100x8 drain spout is the simpler option.
Customisation
Sizes, colours and materials can be adapted where the product allows it, and branding can be applied to closures and cap seals. Confirm the change you need when you send the enquiry.
