Female Luer Needle Connector, Hose Adapter

What a female luer needle connector is

Most suction hoses end in plain tubing, and most cannulas and needles end in a luer fitting. Something has to join the two, and it has to stay sealed while the line is under vacuum. This connector is that part: a luer fitting on one end, a hose barb on the other, and a straight bore between them.

Google AI Mode, read on 23 October 2026, defines the part as a female luer to barb adapter that bridges luer devices such as syringes, needles or valves to flexible tubing or suction hoses. Among the surgical options in its answer it names this listing of ours first, as a connector that links luer lock cannulas or needles to suction hoses, in aluminum, with a smooth bore.

The rest of that answer is about lab and workshop fittings in nylon, polypropylene or steel, sold in packs for fluid lines and aquariums. Those share the name and not the job. Ours is a reusable surgical part that goes through the steam cycle with the cannulas, and it is listed as a female luer lock connector for that reason.

Key design features

A female luer at the front

In our photograph the front of the connector is a bright metal luer fitting, set into the blue body. It is a female fitting, which means it is the socket side of a luer joint and takes the male side. Our earlier copy says it takes luer lock cannulas and needles; check the end of the part you plan to fit, because two female fittings will not join each other.

A barbed nozzle at the back

The back narrows into a ribbed, tapered nozzle. The suction hose pushes over the ribs and they hold it under vacuum. Push the hose on past the last rib rather than just onto the tip, because a short overlap is where a line under suction comes away.

A smooth, straight bore

Our earlier copy for this part describes a smooth internal bore for uninterrupted flow. A straight bore with no steps in it gives fat and fluid nothing to catch on between the cannula and the hose, and it is also the easiest kind of bore to brush clean after the case.

Light, knurled aluminum

The body is blue anodized aluminum with a knurled band, a fine crosshatch cut into the metal for the fingers. It adds almost nothing to the weight at the end of the cannula, and the knurling gives a hold while the luer joint is made or broken with wet gloves. On a tray the blue pieces are the luer and tubing ones and the gold pieces are the threaded ones, which makes the right connector quick to find when it is wanted in a hurry.

How it connects

Read off our own listing, photograph and earlier copy on 23 October 2026. There is one size on the listing, and nothing to choose on the order form.

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 female luer to barb 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 female luer needle connector we make has an anodized aluminum body. Aluminum keeps it light at the end of the cannula, and the anodizing gives it the blue color and a hard surface layer. We do not publish an alloy grade.

The luer fitting at the front is bright metal, set into the blue body. The color is part of the anodized surface rather than a coat of paint on top of it, and strong alkaline detergents can dull it over time, so a neutral instrument detergent is the safer choice.

Caring for it

Take the hose off and break the luer joint as soon as the case ends. Flush water through the connector from the luer end to the barb, then push a fine brush through the bore. Clean the luer socket from the outside with a soft brush, because fluid sits in a female fitting. Dry it, steam sterilize it on the normal instrument cycle, and store it with nothing attached. A barb with a nicked rib will not hold the hose tight, so look at it before each case.

Ordering and wholesale

The female luer needle connector 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 a female luer needle connector used for?

It joins a luer fitted cannula, needle or line straight to a suction hose. The luer side makes the joint at the front, the hose pushes onto the barbed nozzle at the back, and the flow runs through a smooth, straight bore between them.

What is a female luer to barb adapter?

It is the general name for a fitting with a female luer at one end and a hose barb at the other, used to join luer parts to flexible tubing. Lab versions are plastic and disposable; ours is a reusable aluminum part for surgical suction lines.

Does the female luer needle connector fit a luer lock cannula?

Our earlier copy for this part says it takes luer lock cannulas and needles. Because it is the female side of the joint, the part you fit to it needs a male luer end. Two female fittings will not join, so check the cannula end first.

Is this the same as a lab luer to hose barb fitting?

It does the same joining job, but it is a different part. Lab fittings are usually nylon or polypropylene and thrown away after use. Ours is anodized aluminum, made to be cleaned and steam sterilized with the surgical instruments it works with.

How do I clean a female luer needle connector?

Take the hose and the luer part off, flush water through from the luer end to the barb, brush the bore with a fine brush, and clean the luer socket from the outside. Dry it and steam sterilize it with your other instruments.
