It is best used for the relatively short sections to join the dryer outlet to the main vent. Metal tape can also be used to secure the flexible aluminum duct, too, but clamps make it easier to remove the tubing for cleaning.Īluminum foil duct is inexpensive and relatively easy to work with, but it has ribbed walls that can trap lint, leading to potential fire hazard. Foil duct is held in place with dryer clamps or large hose clamps. Transition ducts must not be concealed inside walls or other building cavities and usually have a maximum allowed length of eight feet. Double-check to make sure that this type is approved for your dryer model and allowed by local code. It generally should not be used for the entire duct run.įoil duct can accordion from about 1 to 8 feet, which is usually enough for most installations. Made of flexible aluminum foil with an embedded spiral wire for reinforcement, this type of duct is appropriate for making the transitions from the appliance to the main rigid duct that runs to the outdoor vent hood outlet. The Spruce Home Improvement Review Boardīest for: Transition ductwork in exposed locations.For larger systems we recommend our Angle Rings (RING and RING-U). There are Easy Connect Sleeves (ECS) and Inside/Outside Couplings (IO). We also have other options for connecting the components. Later if you wish to change your system, using a razor blade you can easily cut the silicone. By making a chemical bond, the silicone makes the connection airtight. Wipe the silicone around the outside of the connection. Secure the connection with pop-rivets and silicone caulking. A small-end coupling is used to connect sections of pipe (COUP). A large-end coupling (COU2) is used to make fitting-to-fitting connections. Fittings and small-end couplings are male-end to slip into pipe and flexible hose. This is similar to the way plumbing fittings are connected. How do you make pipe connections? We use the small-end (male-end) and large-end (female-end) method of connecting the components.

Spiral Pipe Ten FootĪlso available in 10-foot lengths when you require large amounts for longer runs, call 80 for more info. Minimum required purchase amount of 40 linear feet. Spiral Pipe Five Footįive foot lengths 18″ inch diameter and larger will be shipped by common carrier. Five foot lengths up to 16″ diameter can be shipped via UPS or FedEx Ground for fast delivery. Spiral pipe is commonly used in dust collection as well as other applications such as industrial ventilation, spray booth stacking, welding booths, paper trim, pharmaceutical clean rooms, etc. Spiral pipe and fittings along with our flexible hoses will complete your piping system. All 22 gauge pipe measures 1/16″ less than the noted diameter on the inside (I.D.). It is considerably stronger than longitudinal pipe of the equivalent gauge. Spiral Pipe DiameterĪvailable in 3-inch to 36-inch diameter in five foot lengths. No painting required, will last years outdoors. Stronger than other pipe – Our pipe is up to 20% stronger than smooth pipe systems of the same gauge, due to the added spiral reinforcement. We manufacture spiral pipe in 18, 20, 22, & 24 gauge galvanized metal. Price listed below is per 5 foot LENGTH for 22 gauge galvanized spiral pipe.Ģ0″ and larger, 4 to 10 working days for fabrication.Ĭlick here for pipe weight and here for allowable negative pressures in round ductingĬlick here for instructions on Cutting Spiral Pipe.
