Prestolok push-in tee, three quick-insertion ends — PBT body
TECTUL · Dispatch across Colombia · Exports to Central & South America
Push-in tee: all three ends receive pneumatic tube directly inserted, with no thread. PBT body with a nickel-plated brass collet and ring at each port. Used to branch a low-pressure air, gas, oil or water line. The manufacturer documents 10 diameters, 4 to 12 mm and 1/8″ to 1/2″.
IMPORTANT: reference data — may differ from the physical product; verify with an advisor before buying.

IMPORTANT
This technical data sheet is a reference guide to the properties of this product type; it is not a quality certificate for the product you are buying. The measurements, dimensions and physical or geometric characteristics of the product supplied may vary by manufacturer, heat and lot, and may even fall outside the cited standards. If any of these figures is critical to your design or build, verify it with one of our advisors against the physical product or the lot's mill certificate, so you can be fully certain of what you are buying. · Original data sheet: tectul.com/en/conduccion-de-fluidos/racores-y-acoples/ficha-tecnica-tee-prestolok.html

2. Frequently asked questions
Do all three ports accept the same tube diameter?
Yes, this reference has equal diameter on all three ends. For a different-diameter branch you need a reducing tee, not documented in this sheet.
Why does the 12 mm weigh more than the 1/2″ if they are close diameters?
Both are separate items in the manufacturer's catalog with their own body geometry; do not assume exact equivalence between a metric size and a nearby imperial one.
3. Application notes
Feasibility
Suitable for branching low-pressure compressed air, gas, oil or water lines without a diameter change.
Installation
Cut the tube square and burr-free; insert fully to the stop at each of the three ports and verify by gently pulling. To disconnect, push the collet toward the body.
Design
Verify the tube's exact outer diameter against the table before purchasing. Confirm the pressure rating with the supplier for the specific application.
4. Technical notice and limitation of liability
The pressures, dimensions, weights and other characteristics in this sheet are theoretical calculation values obtained from nominal properties published in the standards cited (ASME B36.10-2022, ASME B31.3-2024, ASTM A106/A106M-19a, ASTM A53/A53M-24, API Spec 5L 46th ed.). They guide selection; they are not a certificate of conformity for any given lot.
The actual behavior of each lot varies with manufacturing — wall tolerance (up to −12.5%), out-of-roundness, residual stresses — and with the raw material — chemical composition within the ranges the standard allows, heat-to-heat differences. To certify a lot, the tests defined by its product standard are required: tensile test, flattening test and hydrostatic test, documented in the manufacturer's mill test certificate (MTC), which TECTUL supplies upon request; testing of the lot in an independent laboratory can also be arranged.
These values must not be used as the sole criterion in critical or safety applications, or wherever failure of the line may compromise people, property or the environment: in such cases the design belongs to the project's responsible engineer under the applicable code (ASME B31.3, B31.1 or the one governing the installation), with the design temperature, corrosion allowance and load cases of the actual service. Before deciding with these data, consult our technical team.
