Short ventilation reducer with female end

The larger end is female without a gasket to fit over T-pieces and bends.
The small end is male with a double EPDM gasket to slip into Spiral Ducts.

This reducer helps to save installation space, but it increases the flow
resistance compared to RSCLFL long reducers. Standard nominal diameters
up to DN 315 mm are available for pressed pieces at a lower price and with an improved finish.

Reducing pipe (size head) is a piece of pipe used in reducing pipe diameter. The forming process is usually used for reducing the diameter pressing, expanding pressing or reducing the diameter and expanding pressing, for some specifications of reducing pipe can also use stamping forming

The largest end of the GVH Pressed reducer fits over a fitting and the smallest fits into a Spiralo duct. This allows another large fitting of the same diameter to be installed directly onto the reducer.

Our company produces it in large quantities Stainless Steel Duct、Aluminum Duct and HVAC And Ancillary Accessories.
