Adaptor with Luer Lock Connection, Thread to Luer

What an adaptor with luer lock connection is

A threaded cannula and a luer lock syringe do not fit each other. The cannula ends in a threaded hub made for a threaded handle, and the syringe ends in a small luer lock tip. This adaptor sits between them. One end takes the thread, the other takes the syringe, and the cannula can then be worked by hand with the syringe as the handle and the source of suction.

Google AI Mode, read on 23 October 2026, groups this kind of piece with the threaded to luer lock adapters. Its answer says such adapters bridge cannulas, syringes and aspirator systems, and that they are used for fat harvesting, fluid transfer and infiltration. Our earlier copy for this product puts it the same way: a threaded cannula on one end and a luer lock syringe on the other.

Buyers also look for it as a threaded cannula adapter. Whatever the name, the job is to let one set of threaded cannulas serve both the suction line and the syringe.

Key design features

A thread at one end

One end of the adaptor is threaded for a threaded cannula hub. The hub screws on until it seats, and the thread holds it for the rest of the case. Run each cannula onto it by hand before the first case: a hub that turns freely to the seat is on the right thread, and one that binds after a turn belongs to another system.

A luer lock at the other

The other end is a luer lock fitting. A luer lock syringe locks onto it with a short twist, and the same twist the other way frees it. That makes it quick to change a full syringe for an empty one without taking the cannula off the adaptor. For syringe harvesting the plunger is drawn back to make the vacuum and held there, by hand or with a syringe stop lock, while the cannula works. The adaptor only carries that vacuum from the syringe to the cannula; it has no valve of its own.

Short and knurled

In our photograph the adaptor is a short, knurled piece, wider in the middle and narrowing to each fitting. The knurling gives the fingers a hold while a syringe is turned on or off, so the joint to the cannula does not turn with it. Kept short, it adds little to the length of the cannula in the hand. Hold the adaptor, not the cannula, when a syringe goes on or comes off, so the twist goes into the luer joint and not into the thread at the other end.

A gold finish

The adaptor has a gold colored finish over steel, the same look as our adaptor handle with threaded connection. On a tray the gold pieces are the threaded ones, and the blue pieces are the luer and tubing ones, which makes the right part easy to find in a hurry. Keep a spare on the tray as well: it is a small part, and a dropped adaptor ends the syringe work until another one has been through the steam cycle.

Where it is used

The first two columns come from the Google AI Mode answer read on 23 October 2026. They are its words about luer lock adapters in general. The last column is ours.

What it is for, and what it is not for

Each connector in this family joins two particular things. The table sends the other jobs to the piece of ours that does them.

How it compares with the rest of the family

Five connecting pieces make up this family on our site. The ends are read off our own listing for each one, and the prices off each product’s order form.

Materials and finish

Every adaptor with luer lock connection we make is formed from high quality medical grade stainless steel. The steel itself is made to a German specification. We do not publish a grade number.

The gold color is a finish over the steel body, and our earlier copy for this product gives it as gold plating. The knurling is worked into the body, so there is no sleeve or insert to come loose. Both fittings are part of the same piece as the knurled middle.

Caring for it

Take the cannula and the syringe off as soon as the case ends. Flush water through the adaptor from the threaded end to the luer end, then push a fine brush through the bore, which is narrow at the luer side. Scrub the thread and the knurling with a soft brush. Dry it, steam sterilize it on the normal instrument cycle, and keep it with the threaded cannulas so it is on the tray when they are.

Ordering and wholesale

The adaptor with luer lock connection is made by Adas Instruments in our own workshop and sold direct, which is why the price sits where it does against the catalog houses. Order one for a single tray, or in quantity for a hospital list or a distributor line. We do OEM work under your own brand and your own item numbers. Send us a sample and we will hold a run to your pattern rather than ours. Stock items ship from our own workshop. Backorder items take 10 to 12 working days to make. Every instrument carries a three year replacement warranty against manufacturing defects. Production is controlled under an ISO 13485 quality management system.

Frequently asked questions

What is an adaptor with luer lock connection used for?

It lets a threaded liposuction cannula be used on a luer lock syringe. The cannula screws onto the threaded end, the syringe locks onto the luer end, and the surgeon can aspirate, harvest or re-inject fat by hand.

Does the adaptor with luer lock connection fit a Toomey syringe?

No. It takes luer lock syringes, which lock on with a short twist. A Toomey syringe has a wide tip that pushes on, and it needs a cannula with a Toomey hub, which our cannula order forms offer as a hub choice.

What is the difference between a Luer Lock and a luer slip?

A luer slip joins by pushing the taper in and relies on friction alone. A luer lock adds a short thread, so the joint is turned on and stays on. Under suction or pressure the lock is the one that does not pull apart.

Can I use the adaptor with luer lock connection on the suction machine?

Not directly. Its luer end is made for a syringe. To run a threaded cannula on suction tubing, use our adaptor handle with threaded connection, which has a barbed nozzle at the back for the tubing.

How do I clean a thread to luer adaptor?

Take everything off it, flush water through from end to end, and brush the bore with a fine brush, because the luer side is narrow. Scrub the thread and the knurling, dry it, and steam sterilize it with your other instruments.
