ALNOR SEGMENT BEND WITH GASKET BSL-250-90 — duct elbow segment with gasket, Ø250 mm, 90°

ALNOR SEGMENT BEND WITH GASKET BSL-250-90 is a 90° duct elbow segment designed for circular ventilation and air-conditioning systems with a nominal diameter of 250 mm. The component incorporates a molded gasket to improve air tightness at joints and is intended for redirecting airflow in duct runs within commercial and residential HVAC installations. The segment is compatible with round ductwork of the same nominal diameter and is used where a compact, reliable change of direction is required.

Advantages

The segment bend provides a secure, gasketed connection that reduces air leakage and improves system efficiency. Its 90° curvature is manufactured to maintain smooth internal airflow and minimize pressure drop. The design allows straightforward alignment and assembly with other circular duct components, helping to reduce installation time. Materials and finishing are suitable for standard ventilation environments and support durable operation when installed according to recommendations.

Suitable for

• Redirecting airflow in circular ventilation and air-conditioning ducts
• Commercial HVAC systems including offices and retail spaces
• Residential ventilation installations and apartment systems
• Retrofit projects where a gasketed, airtight elbow is required

Key specifications

• Nominal diameter: 250 mm
• Angle: 90° elbow segment
• Connection type: gasketed joint for airtight sealing
• Shape: circular/round duct segment
• Typical application: ventilation and air-conditioning ductwork

How to use

Position the segment bend between matching 250 mm circular duct sections, ensuring the gasket faces the mating flange or socket. Align the segment so the curvature provides the intended change of direction, then secure adjoining duct components using the appropriate clamps, rivets or screws per system design. Check the gasket seating for continuous contact around the joint to maintain airtightness. After installation, perform a visual inspection and, if possible, a leak test as part of system commissioning.

Usage recommendations

For reliable performance, install the gasketed segment with compatible 250 mm round duct components and follow local HVAC installation standards. Avoid excessive bending or forcing of the segment during assembly. Where condensation or aggressive environments are expected, consider appropriate corrosion protection or compatible materials for the complete duct run. Periodically inspect joints for integrity and re-tighten fastenings if necessary.
