T-fitting (screw) Comap 18 JEVCO – compression branching fitting for piping systems

Comap 18 JEVCO screw-type compression T-fitting is a mechanical branching fitting designed to create a reliable tee junction in piping systems. Manufactured by Comap, this compression trójnik provides a secure connection between three pipe runs using a screw/compression assembly that ensures mechanical holding and resistance to leakage when installed correctly. The fitting is intended for plumbing and heating applications where a durable, compact branching solution is required.

Advantages

This compression T-fitting offers a robust mechanical connection without the need for hot-work or soldering, simplifying installation in confined or retrofit spaces. The screw/compression design provides consistent axial force to maintain a leak-resistant seal and reduces the risk of joint movement under thermal cycling. Its compact form factor allows installation in tight layouts while maintaining straightforward maintenance and replacement access.

Suitable for

• Domestic and commercial plumbing systems
• Heating and radiator pipe connections
• Retrofit and repair works where soldering is impractical
• Systems using compatible metal or plastic pipes suitable for compression fittings

Key specifications

• Type: screw-type compression T-fitting
• Function: mechanical branch (tee) connection for three pipe runs
• Application: plumbing and heating installations
• Installation method: compression/screw assembly requiring standard plumbing tools
• Design characteristics: compact body for space-constrained installations and maintenance access

How to use

Prepare pipe ends by cutting square and deburring to ensure full contact with the compression seats. Slide the compression nut and ferrule onto each pipe, insert pipes fully into the fitting body, then tighten the compression nuts by hand and finish with a suitable wrench to the specified torque or until a secure, leak-free joint is achieved. Follow accepted plumbing practice for support and alignment to avoid imposing stress on the fitting. Pressure-test the assembly after installation according to system requirements.

Usage recommendations

Use the Comap 18 JEVCO T-fitting only with pipe materials and diameters that are compatible with compression fittings. Avoid overtightening to prevent deformation of ferrules or pipe wall damage. Where system standards or local codes require, employ thread sealant or appropriate sealing methods on mating threads and adhere to manufacturer guidance for maximum operating pressure and temperature limits.
