Verplas 150mm Round 90 Degree Bend Duct Fitting

Verplas 150mm Round 90 Degree Bend Duct Fitting

The Verplas VKC360 is a 150mm round 90° elbow bend for the Verplas System 150 rigid duct range. It provides a full right-angle direction change in 150mm duct runs, suitable for routing around structural elements, joists, walls, or ceiling voids. The fitting is push-fit compatible with all System 150 duct pipes and fittings, and is made from white uPVC for lightweight, consistent installation.

Material
Low Resistance
Smooth Bore Sweep
Pressure Drop: Each 90° bend adds equivalent duct resistance. Where space permits, using two VKC361 45° bends instead of one 90° elbow reduces the pressure drop penalty and can improve fan performance in longer duct runs.
Key Features
Full 90° Direction Change
Provides a clean right-angle turn in a 150mm rigid duct run — ideal for corners, ceiling-to-wall transitions, and routing around structural elements.
Swept Elbow Profile
The swept elbow geometry minimises internal turbulence compared to a sharp mitre bend, reducing pressure drop and airflow noise at the change of direction.
Push-Fit Spigots
Male spigots on both ports connect push-fit to female sockets on duct connectors and other fittings — no tools, tape, or sealant needed.
White uPVC
Manufactured from white uPVC consistent with System 150 duct pipe and all other VKC-series fittings.
System 150 Compatible
Designed to mate with all VKC-series 150mm fittings including pipes, connectors, T-pieces, telescopic pipes, and terminal valves.
Fan & MVHR Use
Suitable for single-room extract fans, dMEV, and MVHR distribution runs wherever a direction change is required.

Frequently Asked Questions
Is it better to use a 90° or two 45° bends?
Two VKC361 45° bends create a gentler sweep with lower total pressure drop than a single VKC360 90° elbow. If fan duty is marginal or noise is a concern, prefer the two-bend approach where space allows.
Can I use this bend in any orientation?
Yes — the VKC360 can be oriented in any plane: horizontal, vertical, or angled. Secure the duct run with pipe clips to prevent lever loading on the bend body.
Does the 90° bend affect noise levels?
Direction changes increase turbulence and can raise duct noise. Using a swept elbow and keeping airflow velocity within recommended limits minimises this effect.
How many 90° bends can I use in one duct run?
There is no hard limit, but each bend adds resistance. Most fan specifications will provide a maximum equivalent duct length — count each 90° bend as its equivalent length when designing the run.
