Piping, Fittings & Accessories
The all welded stainless steel clamp is fitted with a heavy duty, continuously reusable O-ring sealing gasket. The locking mechanism is so sturdy that it is backed with a “forever” guarantee. There are no punched or perforated parts to fatigue or bend. In fact, if it ever breaks, tears or becomes unusable, return it for a free replacement.

Clamp Together Duct Specifications
Product Description: The system is a full line of duct and components. All parts are of standard sheet metal construction with a rolled lip applied to each end of the component. An all stainless over-center locking clamp is used to encompass the rolled lips, pull them together and then securely join them. Adapters enable connection to virtually and machine or existing duct.
Clamp: The lifetime guaranteed clamp is fitted with a “winged O-ring” gasket made of N-butyl rubber. The gasket is designed to fully encompass the entirety of the rolled lips including the area formed by the “v” between the rolled lips. Other gasket material is available (see below).
Duct and Adjustability: The duct is a nominal 5’ length. Adjustable sleeves and adjustable components enable the installer to quickly make odd lengths and to adjust for a proper fit. To utilize this feature, a cut piece of pipe is slid into the sleeve or fitting and secured with an O-ring and standard clamp.
STANDARD PRODUCT
Materials: Material Duct and Components are available in galvanized carbon steel and stainless (304-316) as a standard.
Gauges: Duct Standard Gauges for the duct are 26 ga for 3”, 24 ga for 4-6”, 22 ga for 7-12” and 20 ga for sizes 13-22”. Elbows are typically one gauge heavier than standard duct gauge. All components (branches, reducers etc) are of 18 ga material.
PRODUCT OPTIONS
Gasket Materials: Viton, and Red Silicone gaskets and O-ring material are also available.
Gauges: All duct can be provided in standard configuration in one ga heavier (24 in 22, 22 in 20and 20 in 18). Rolled lips can be applied to Gauges up to 10 ga by applying a rolled lip collar to fully welded duct and components. Heavy tubed elbows are available.
PRESSURE RATING: The rolled lip on the duct and fittings act as a stiffening ring and therefore allow the product to withstand much higher pressures than normally associated with spiral or other rolled duct. The duct is typically installed with the confidence in pressure applications up to 40” negative water column pressure. Higher pressures are available, as are positive pressure ratings.
