What Is a Hoffman Screw Used For?
A Hoffman screw is clamped across rubber tubing in apparatus such as a reservoir outlet or a gas-delivery line. Turning the screw presses the tube shut gradually, so the flow can be cut to a slow, steady rate or shut off.
Frequently Asked Questions
How does a Hoffman screw differ from a Mohr pinch clip?
A Mohr clip is a spring pinchcock meant mainly to open or close a tube; the Hoffman screw is tightened by hand and can hold the tube partly open for a set flow.
Can rubber tubing be quoted together with the Hoffman screws?
Yes. Tubing is a separate catalogue item, linked below, and can be added to the same enquiry.
What should an export enquiry include?
The quantity, the destination country and port or city, delivery terms such as FOB or CIF, packing or labelling needs, and any tender reference.
