BFM® spigots, or BFM® collars, are manufactured out of 304 and 316 stainless steel in a range of standard sizes from 100 mm (4 in) up to 1,650 mm (65 in) in 50 mm (2 in) increments that can accommodate virtually any process environment. Additionally, for special applications, C22 Hastelloy is available from 100 mm (4 in) to 500 mm (20 in) in 50 mm (2 in) increments.

  • The spigot design incorporates a slight taper allowing the unit to be trimmed to an exact fit for any existing pipe or installation.
  • A BFM® collar has a 52 mm (2 in) tail that can be cut back to suit existing pipework.
  • BFM® Collars or BFM® Spigots for Tool Release installations require a 6 mm (15/64") hole in the top rim of the spigot. Pre-drilled TR spigots are available for purchase with your BFM® TR Connectors.
  • Jacob flanges are available that allow the BFM® collars to be installed or removed in seconds without tools. We can provide 150# flanges for more heavy duty applications, or ferrule ends for sanitary applications.
  • For more details, view the spigot drawing.
Note: For applications where electrostatic charge may build up, we recommend using a grounding strap to connecting the two BFM® spigots together.
