Pick this clip when you want to fit it onto tubing that is already connected, thanks to the swing-out bottom plate, and when you need a choice of chrome or brass plating. The brass screw clip is a chrome-plated brass alternative, and the Mohr-type clips, a spring pattern sold in packs of 10, suit simple open-or-shut use.
What Is the Hoffman Clip Used For?
A Hoffman clip is a screw clamp that squeezes rubber tubing between two plates. Closed part of the way it slows the flow of a liquid or gas; closed fully it stops it. In school and college labs it is used on the delivery tubes of gas preparation set-ups, on the water lines of condensers, on siphons and aspirator bottles, and on the suction tube of Hare’s apparatus — a small fitting that school chemistry and physics labs keep in quantity.
To fit it, swing the bottom plate aside, lay the tubing between the plates, close the plate and tighten the clip gradually until the flow is right. Do not overtighten thin-walled tubing, which can split, and release the clip when the apparatus is put away so the rubber does not take a permanent set. The plating helps the clip resist corrosion in normal use, but wipe off acid or salt spills and dry the clip before storing it.

Frequently Asked Questions
What is a Hoffman clip used for?
It controls or stops the flow through rubber tubing. Tightening it partly reduces the flow, and closing it fully shuts the tube, which is useful on gas delivery tubes, condenser water lines and siphons.
How is the tube fitted into the clip?
The bottom plate rotates on one side. Swing it open, place the tubing between the moving and fixed plates, swing the plate back and tighten the clip.
What is the clip made of?
It is listed as iron, chrome or brass plated. Say which plated finish you want when you send your enquiry.
What size of tubing does it fit?
The listing does not state a size range. Give the outside diameter of your tubing when you enquire and JLab will confirm the fit.
Who makes the Hoffman clip, and how soon can it be dispatched?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana. The minimum order is 10 units; orders usually leave within 7–10 working days after each clip is visually checked, and export transit time depends on the destination.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of laboratory apparatus and fittings in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The Hoffman clip is made at JLab’s own works and not bought in from a trader, so schools, colleges, dealers and importers order it factory-direct, every clip is looked over before it is packed, and repeat orders are handled by the manufacturer. With worldwide exports, JLab can serve buyers in every region — for instance Kyrgyzstan in Central Asia, Afghanistan in South Asia, Cameroon in Central Africa, Eswatini in Southern Africa and Qatar in the Middle East. Tender information is available on the JLab lab tenders page.
Tubing and Apparatus to Use It With
- Rubber Tubing — natural rubber laboratory tubing for the clip to close.
- Silicone Rubber Tubing — synthetic silicone tubing with a square outer profile that sits flat on the bench.
- Hare's Apparatus On Stand — density apparatus whose suction tube is closed with a clip.
More fittings are listed in the School Lab Equipment range.
