Ventilation end cap, Ø50 mm

The Ø50 ventilation end cap is a compact yet essential component for the correct operation of indoor drainage and venting. It is installed on the top section of a 50 mm sewer pipe (terminated above the roof or routed into a technical ventilation zone, depending on the project) and performs two key functions: it protects the pipe from precipitation and debris while maintaining free air exchange between the drainage system and the atmosphere. As a result, the system runs more steadily, more quietly, and without unpleasant “surprises” such as odors.

When water is discharged (sink, shower, household appliances), pressure fluctuations occur inside the pipework. If there is not enough air intake, water in traps can be partially siphoned out, reducing the effectiveness of the water seal—this leads to gurgling sounds and unpleasant smells indoors. The ventilation end cap helps prevent these issues: dedicated airflow openings on the inner side of the cap allow air in, and the stack or vent line receives the “make-up” air needed to compensate for negative pressure. This is particularly important in private houses, cottages, and systems with a septic tank or multiple draw-off points, where drainage loads can change suddenly.

Structurally, the product is designed as a cylinder with a mushroom-style top cover. This shape forms a reliable weather hood: rain and snow do not enter the pipe directly, while the gap between the body and the cover maintains airflow even in bad weather. The end cap is made of a polymer material compatible with polypropylene drainage systems: it does not rust, is corrosion-resistant, withstands moisture and household chemicals, and keeps a neat appearance over long-term use. The operating temperature is up to 95°C, which suits domestic wastewater, including occasional hot discharges.

Installation is quick and convenient: a socket connection with a sealing ring provides a tight, secure fit on Ø50 pipe without adhesive or complex tools. For proper installation, simply clean the seating area, check the gasket, and push the part fully into place—resulting in a leak-tight, stable joint.

Advantages of the Ø50 ventilation hood:

protects the vent outlet from rain, snow, leaves, and debris;

maintains correct sewer ventilation through dedicated airflow openings;

reduces the risk of odors and trap seal loss;

resistant to corrosion and humid environments;

operating temperature up to 95°C;

easy socket installation with a sealing ring;

neat appearance and long service life.

The Ø50 ventilation end cap is an optimal choice for anyone who wants to improve the reliability of sewer venting, protect the pipe termination, and ensure correct system operation year-round.
