Who it suits
Is it right for you?
Great for
- Carp anglers fishing weed, gravel or silt. The heavy, supple tubing is designed to sit tight to the lakebed while the colour options help the rig blend in.
- Anglers using Korda tail rubbers and clips. The 0.75 mm bore is designed around that Korda-compatible setup, making it a straightforward addition to familiar rigs.
Maybe skip if
- Anglers wanting the absolute simplest, lightest presentation. This is deliberately heavy tubing, so it may be more than you need when pinning and concealment aren’t priorities.
- Anyone using unusually bulky end tackle. The 0.75 mm bore could limit compatibility with larger components, so check your connections before cutting a full rig’s worth.

The full rundown
Everything you'll want to know about the Korda Dark Matter Tubing
There are loads of clever bits of terminal tackle about, but sometimes you just need the boring stuff to do its job properly. Korda Dark Matter Tubing falls firmly into that camp. It’s made to keep your end tackle pinned down, tidy and a bit less obvious on the lakebed.
The big selling point is the tungsten-impregnated construction. That gives the tubing a useful bit of weight, helping it settle rather than floating or lifting away from the bottom. If you’re fishing a clean gravel area, a soft silty spot or a weedy margin, that can make your whole presentation look more natural.
It’s supplied in a 2-metre length, which is plenty for chopping down into the rig lengths you actually need. You’re not tied to one fixed size, either. Make it short around a lead setup, run it longer for extra cover, or trim it to suit the contours of the spot. Just get the scissors out and crack on.
The tubing has a 0.75 mm bore. That’s a useful middle-ground size for the sort of carp and coarse terminal tackle most anglers are likely to pair it with. It’s designed to work with Korda tail rubbers and clips, so it slots neatly into a familiar setup rather than leaving you scratching your head at the tackle box.
Colour choice is another strong point. You get Weed Green, Gravel Brown and Silt, covering the main sorts of lakebed you’ll come across. Obviously, a colour won’t magically disappear over every bottom under the sun, but matching the tubing to the area is a sensible little edge. Especially when fish are feeding confidently but still giving the rig a proper once-over.
The construction is soft and supple, too. That matters more than it might sound. Rigid tubing can sit proud over little dips and bumps, creating a presentation that looks fine in your hand but not quite so tidy once it’s landed. Dark Matter Tubing is designed to follow those lakebed contours instead.
Threading tubing can be a proper faff when it’s too tight, too stiff or prone to kinking. This stuff is designed to be easy to thread, which should make rig prep less of a chore. Take your time, keep the connection clean and don’t try forcing a bulky component through the bore just because you’re in a rush.
There’s plenty of flexibility in how you can use it. Pair it with high-breaking-strain braid or fluorocarbon, use it alongside Korda clips and tail rubbers, then cut the length to suit the swim. It’s the sort of component that earns its keep across different rigs, rather than being pulled out for one very specific situation.
For carp anglers, the obvious use is creating a concealed, pinned-down final section. For coarse-match anglers, it has a place when you need a neat, unobtrusive presentation around features and want the end tackle kept close to the deck. It won’t catch fish on its own, mate, but it can remove one more reason for a wary fish to bin the rig.
The only thing to keep in mind is that heavy tubing isn’t automatically right for every situation. If you’re fishing a light, open-water presentation where you want minimal material, this may feel a bit over the top. But when concealment, bottom contact and a tidy rig are the priority, Dark Matter Tubing is bob on. It’s dependable kit that helps you get the basics right — and the basics still put plenty of lumps on the bank.

Our take
The angle
This is all about keeping the final section of your setup close to the deck. Tungsten-impregnated tubing adds weight without turning the tubing into a rigid, awkward chore to thread.
The colour choices are bang on for matching common lakebeds, and the soft construction should follow contours rather than bridging over little humps and hollows. That’s handy when presentation and concealment matter.
What you’re buying
Heavy tubing that follows the deck
Korda Dark Matter Tubing is tungsten-impregnated, heavy and supple. The idea is simple: cover the end section, help pin it down and let it follow the contours of the lakebed rather than standing proud over little dips and hollows.
You get 2 metres on the spool, with a 0.75 mm bore. That gives you room to cut the tubing to the length your rig needs, whether you’re building a compact setup or want a longer section for extra concealment. It’s available in Weed Green, Gravel Brown and Silt.
Worth knowing. The tubing is compatible with Korda tail rubbers and clips, and is suitable for high-breaking-strain braid and fluorocarbon. Check your components before threading, especially if you’re using anything unusually bulky.
Where it earns its keep
A tidy choice for wary fish and feature fishing
This is a good fit for carp anglers fishing over weed, gravel or silt who want the rig to blend in while staying close to the bottom. Match the colour to the area, cut a sensible length and make sure it settles naturally when the rig is presented.
It also suits coarse-match anglers who like a neat, controlled terminal setup around features. The tubing can help keep the end section organised and unobtrusive, particularly when fish are feeding close to the deck and you don’t want loose bits waving about.
It’s less compelling when you’re deliberately fishing a very light presentation or don’t need extra weight and concealment. In those situations, the added material may be more faff than benefit.
Quick answers
The bits you’ll want to know
Which colour should you pick? Weed Green is the obvious shout over weed, Gravel Brown suits gravelly bottoms and Silt is aimed at softer, silty lakebeds. Think of it as sensible blending, not camouflage magic.
How much should you use? There’s no one-size-fits-all answer. Cut it to suit the rig, the bottom and the amount of concealment you want. Keep it neat and avoid using a huge length just for the sake of it.
Worth knowing. Thread it carefully and make sure the tubing is sitting properly around the connection and clip. A tidy final section is the whole point, so don’t let rushed rig prep undo the job.
