Getting Started with BFM® fittings
We have Authorized Distributors who will help work through what you want to achieve and how BFM® fitting can improve your plant.
Rings
LM4 is available with stainless steel or plastic support rings to help keep the walls of the connector open.
Ideal for vacuum applications or longer lengths.
Tapered
LM4 is available as a tapered version where different entry and exit diameters are required.
Also often used as a simple hopper solution.
Tool Release
For added security, this option has a significantly firmer snap-band that makes it virtually impossible to remove by hand and requires a specially shaped tool.
PVC Pipework
LM4 connectors used in PVC pipe production.
