Crimp Tee SiGMA-Li MT16 — 16×16×16 mm plumbing fitting

Crimp tee SiGMA-Li MT16 — 16×16×16 mm plumbing fitting is a compact press-fit T-connector designed to create a branch in metal and multilayer piping systems. Intended for use in potable water and heating networks, the tee provides a right-angle branch with 16 mm connections on all three ports. The fitting is produced to work with a compatible crimping tool and sealing ring to form a secure, low-maintenance joint suitable for indoor plumbing installations.

Advantages

The design of this 16×16×16 mm crimp tee offers consistent geometry for reliable alignment and simplified assembly. Using a press-fit connection reduces installation time compared with soldering or threaded joints and minimizes the need for hot work. When installed with the appropriate sealing ring and crimping tool, the tee provides leak-resistant connections and stable mechanical performance under normal operating conditions.

Suitable for

• Creating branch connections in domestic water supply systems
• Branching runs in heating circuits and radiator feeds
• Installation in concealed and exposed indoor plumbing
• Replacement or modification of existing press-fit lines

Key specifications

• Connection type: press-fit (crimp)
• Nominal dimensions: 16×16×16 mm
• Application: potable water and heating systems
• Compatible with: metal and multilayer press pipes and corresponding crimp rings
• Installation environment: indoor plumbing, concealed or exposed

How to use

Prepare pipe ends by cutting square and deburring the inside and outside faces to ensure correct seating. Slide the compatible crimp ring onto each pipe, insert the pipe fully into the tee until it reaches the predefined stop, and verify alignment. Use a compatible crimping tool sized for 16 mm rings and perform the crimping operation according to the tool manufacturer’s instructions to compress the ring uniformly. After crimping, inspect each connection visually and, where required by local practice, perform a pressure test to confirm leak-tightness.

Usage recommendations

Always use sealing rings and crimping tools that match the 16 mm dimension and are approved for use with metal or multilayer pipes. Store fittings in a dry environment and protect open ends from contamination before assembly. Follow local plumbing codes and the tool manufacturer's safety guidelines during installation.
