We have been on the market since 1991. From the very beginning, the company's goal is to produce fittings for the construction, modernization and renovation of pipelines.

Trying to meet the requirements of our customers, we have been operating on the market of electrofusion fittings since 2018 as TQ-Fitting, but we took our first steps in 1991, when the Trans Quadro brand was created, one of the founders of which was Mr. Adam Oczkowski.
Within 30 years, we have managed to build a wide distribution network in most European Union countries and abroad.

TQ-Fitting is a leading and one of the most experienced producers of polyethylene fittings on the European market. Trust and diligence are the pillars of our development policy, thanks to the constantly growing trust of customers in our products, we are able to face more and more difficult technological challenges every day.


We have always believed that quality is our greatest asset, which is why our fittings are made to the highest standards.

We use raw materials of the highest quality, thanks to which our products comply with the applicable standards on the water and gas market. The company TQ-Fitting has created a modern production plant, it is there that our products are created and improved, and the finished ones are directly tested. This guarantees the safe use of our product.

The production plant in which our fittings are made has been built according to the highest European standards. Our main goal is to ensure the highest possible quality of manufactured and distributed products, thanks to which we can meet the requirements of the most demanding customers.
