Gas flexible pipe Famas PSR-07ANT-025 DN25 250–450 mm

Flexible gas pipe Famas PSR-07ANT-025 DN25 250–450 mm is a corrugated metal hose designed for indoor gas installations where short axial compensation and slight alignment adjustment are required. The product features a nominal diameter DN25 and an adjustable effective length range from 250 to 450 mm, permitting secure connections between gas appliances, valves and fittings while accommodating thermal expansion and small positional deviations during installation.

Advantages

The construction provides flexibility combined with mechanical strength, enabling reliable gas tightness under normal operating conditions. Compact adjustable length reduces the need for precise measurement and cutting on site, saving installation time. Materials and design minimize transmission of vibration and allow for small axial movements caused by thermal changes, ensuring a stable connection to fixed piping and appliances.

Suitable for

• Connecting indoor gas appliances to fixed gas supply lines
• Short compensation runs where space is limited
• Installations requiring slight alignment adjustment between fittings and equipment
• Residential and commercial indoor gas distribution where DN25 is specified

Key specifications

• Nominal diameter: DN25
• Adjustable length range: 250–450 mm
• Corrugated metal hose construction for flexibility and strength
• Designed for indoor gas distribution and appliance connections
• Provides short axial compensation and slight misalignment accommodation

How to use

Install the flexible pipe between the gas appliance and the fixed gas line or valve, ensuring that connections are made with compatible fittings and tightened according to the appliance and installer instructions. Adjust the pipe to the required length within the 250–450 mm range without forcing or overstretching the hose. After installation, perform a gas tightness test and check for leaks using approved detection methods before putting the appliance into service.

Usage recommendations

Use only for indoor gas applications and follow local regulations and standards for gas installations. Ensure compatible thread types and sealing methods are used at both ends. Avoid permanent bending, excessive torsion or mechanical stress on the flexible pipe. Regularly inspect connections and condition during scheduled maintenance and replace the pipe if any damage, corrosion or deformation is detected.
