Product Description

Title Line

Available in Stainless Steel T304L and T316L , as well as C22 Hastelloy. They are available in a range of exact sizes, eliminating the imprecise nature of hose-clamp sleeve type connection widths and ensuring a perfect fit with the BFM® connector.

  • The design is slightly tapered, so the OD at the top of the tail is 5mm / 13/64”  greater than the base.

  • 89mm (3 1/2") in total length - made up of a head of 37mm (1 29/64") and a 'tail' that is 52mm (2”) long.

  • The tail can be easily cut down or cut on an angle to suit your existing tubing or pipework.

For applications where there is a possibility for static build-up, e.g. wood dust, flour, milk powder etc., we recommend using a static dissipative wire (strip), connecting the two BFM® spigots together.

Frequently Asked Questions

Title Line
What is the smallest gap a BFM® connector can fit into?

The smallest gap you can have between the BFM® spigots is 65mm (2.5") for an 80mm (3") long BFM® connector. Note that this gap may not be suitable for frequently changed connectors or for those with more than just a slight vibratory movement. Please also take some time to read the fitting instructions in the installation guides.

Can BFM® spigots be connected to aluminum pipes?

Because the stainless steel spigot will not directly weld to aluminium, another technique will need to be used, such as welding a flange to the spigot and then attaching by bolt or rivet to the pipe or using a Morris coupling to attach the spigot to the existing aluminium pipe.

Is it possible to get BFM® spigots manufactured in different thicknesses?

No - all of our spigots are manufactured with the same thickness of steel - 2mm. The 100mm BFM® spigots are sized to fit standard 'dairy' tube, which is measured externally, all other BFM® spigot diameters are measured internally to accommodate nominal bore standard tube.

Can we use Morris Couplings rather than welding the spigots to our pipework?

It is possible, however, Morris couplings need straight length equivalent to 1 1/2 times coupling length, so there would need to be enough space to fit this. You would want at least an inch of the spigot to remain to get enough clamping area.

I have a square pipe that I want to connect a BFM® to - what's the best way of doing this?

Square-to-round transition adaptations are easily achieved. Please contact us or speak to your local distributor for help.


How can I cut the Spigot to an exact imperial size?
BFM® spigots are manufactured to metric standards, with nominal diameters starting at 100mm (3 15/16 inches), and going up to 1,650mm (64 61/64 inches) in 50mm (1 31/32 inch) increments. 
This diameter is measured at the end of the tail of the spigots, and there is a very slight taper from the head to the base of the spigot meaning the head is actually around 6mm (15/64”) larger than the tail.

To obtain an exact Imperial Pipe Size for your spigot tail, simply cut the tail of the spigot to an appropriate length where the taper will be an Imperial equivalent measurement.
