ALNOR NS-150 nypl connector without gasket, duct fitting DN150

ALNOR NS-150 nypl connector without gasket, duct fitting DN150 is a metal push-fit coupling designed for circular ventilation ducts with a nominal diameter of 150 mm. The connector provides a mechanical connection between duct sections and compatible components without a sealing gasket, offering a compact and rigid joint for installations where a gasketless connection is acceptable.

Advantages

The nypl connector is manufactured from metal for strength and dimensional stability, enabling reliable alignment and support of circular ducts. Supplied without a gasket, it simplifies assembly and reduces parts count while keeping the connection mechanically secure. Its standard diameter makes it compatible with common 150 mm ventilation components and accessories.

Suitable for

• Air distribution and supply ducts in residential and commercial HVAC systems
• Exhaust ventilation lines where a mechanical, non-sealed joint is acceptable
• Temporary or semi-permanent ductwork installations that require quick push-fit connections
• Systems where metal fittings are preferred for durability and fire resistance

Key specifications

• Material: metal construction for mechanical strength and dimensional stability
• Nominal diameter: 150 mm for compatibility with DN150 circular ducts
• Connection type: push-fit (nypl) coupling providing a mechanical joint without a gasket
• Application: designed for circular ventilation duct systems (supply and exhaust)
• Finish: metal surface suitable for standard HVAC installation conditions

How to use

Insert the edge of a DN150 circular duct into the nypl connector until it seats fully and the mechanical lip engages. Ensure mating duct ends are clean, free of sharp burrs and aligned to avoid distortion of the joint. For installations where airtightness is required, use an appropriate external sealing method or select a gasketed connector; this product is supplied without a gasket and does not provide a factory-installed air seal. Secure the joint as needed with appropriate clamps, screws or tape following local HVAC practice.

Usage recommendations

Use the ALNOR NS-150 nypl connector in systems where a mechanical connection is sufficient. Inspect joints after installation and consider supplementary sealing when required by airflow performance, building regulations or noise control. Store fittings flat in dry conditions to avoid deformation prior to installation.
