Tapered threaded transition coupler, type LX-CT

Q: Will the coupler pass GOST and lab testing?

Yes. The splice is full-strength — splice strength ≥95% of the bar's ultimate tensile strength, compliant with GOST 34278-2024. We provide the test report and a free trial kit for incoming inspection and the lab.

Q: How much is the Tapered threaded transition coupler Type LX-CT?

The price depends on the diameter and batch volume — we send the current price for your project within the business day.

Q: Why is a coupler better than welding or a lap splice?

The thread is rolled onto the bar with no loss of cross-section, the splice is full-strength to the rebar body, installation is faster than welding and with no length lost to lapping — rebar savings of up to 25%.

In shortThe Type LX-CT tapered transition coupler is a conical coupler for splicing rebar of different diameters (Ø20–40 mm) in one connection with accelerated assembly thanks to the conical thread. Used at rebar cross-section changes over the height of a structure and when splicing different reinforcement. Full-strength splice per GOST 34278-2024, steel 45/40Kh, LOMAX TU.

Applications

Rebar section transition and joining of different reinforcement.

Why it pays off with the LOMAX factory

In-house production

We cut and roll the threads ourselves — we don't resell imported systems (RollCon, Dextra, Bartec). That makes our price structurally lower.

Lower price than imported systems

Direct factory prices, proven over 3 years of supply. We'll beat your current supplier.

GOST 34278-2024 test report

Full-strength splice ≥95% Rm. We include the test report in the document package for the site.

Free trial kit

For incoming inspection and the lab — we remove the risk before the first delivery to site.

Shipping across Russia

From stock and to order, any region and the CIS. Common Ø sizes ship immediately.

Help with the specification

We'll match types and volume to your project and count the couplers from your drawings.

Frequently asked questions

Will the coupler pass GOST and lab testing?

Yes. Splice strength ≥95% of the bar's ultimate tensile strength, compliant with GOST 34278-2024. We provide the test report and a free trial kit for incoming inspection.

What does the price depend on?

On the diameter and batch volume. We send the current price for your project within the business day — usually below your current supplier.

Do you ship across Russia?

Yes, we ship to all regions of Russia and the CIS. Common sizes are from stock, the rest are made to order.

Why is a coupler better than welding or a lap splice?

The thread is rolled with no loss of cross-section, the splice is full-strength to the rebar body, installation is faster than welding and with no rebar overrun on lapping — savings of up to 25%. More — in comparing coupler / welding / lap splice.
