Brass blanking cap FERRO ZAS4Z 1" for pipe fittings

FERRO ZAS4Z 1" brass blanking cap is designed to close or seal open pipe ends and fittings in plumbing, heating and water supply systems. Manufactured from brass, it provides resistance to corrosion and mechanical wear while offering a removable and reliable closure for both temporary and permanent applications. The cap fits standard 1" threaded connections and serves as a practical part for maintenance, pressure testing and termination of service lines.

Advantages

The brass construction combines durability with corrosion resistance, ensuring long service life in wet and heated environments. The threaded design allows straightforward installation and removal without special tools, and the precise thread machining ensures a secure fit to prevent leaks. Its compact form makes it suitable for confined spaces and for use during system flushing, repairs or when capping unused branches.

Suitable for

• Sealing open ends of 1" threaded pipes and fittings
• Temporary capping during installation and maintenance
• Pressure testing of plumbing and heating circuits
• Permanent termination of service lines where a removable cap is preferred

Key specifications

• Material: brass for enhanced corrosion resistance
• Connection type: 1" threaded cap compatible with standard pipe fittings
• Application environment: potable water, heating systems, general plumbing
• Design: removable threaded closure for temporary or permanent use

How to use

Before fitting, clean the mating threads and remove debris or old sealing material. Apply an appropriate thread sealant (such as PTFE tape or liquid thread sealant) on the male threads of the pipe to ensure leak-tightness. Hand-tighten the cap onto the threaded pipe until snug, then use a suitable wrench to make a further quarter to half turn if required; avoid over-tightening to prevent damage to threads or deformation of the cap. For pressure testing, follow system-specific procedures and safety precautions.

Usage recommendations

Check compatibility with the fluid and temperature range in your system before installation. For potable water installations, use approved sealing materials. Inspect threads periodically for wear if the cap is used in long-term installations and replace if corrosion or thread damage is observed.
