Custom Fabricated Metal Hose & More
Flextrol offers a broad range of hose for virtually any application imaginable. Please make a selection from the categories below for more information:
Corrugated Flexible Metal Hose
Our standard corrugated metal hose is made by forming annular corrugations into a thin wall welded tube. It is pressure tight and ideal for vibration, continuous flexing and, when properly designed and installed, thermal expansion and contraction. Helical hose is also available. We offer T-321 stainless steel, T-316 stainless steel, bronze, monel, and hasteloy corrugated hose.
Flexible Metal Jumpover Hose
Flextrol also provides jumpover hoses to interconnect the numerous jackets in a jacketed piping system. These hoses are available in standard diameters of 1/2″, 3/4″ and 1″ male NPT pipe. Jumpover hoses are made from stainless steel flexible hose, and can be insulated with fiberglass/silicone covers. Standard lengths include 24″,28″ and 30″ with other lengths available.
The Illustration shows how jumpover hoses interconnect jacket sections in series. The photograph shows a typical valve jacket to pipe jacket connection.
Flex-C-Loop Hose
Our new Flex-C-Loop provides flexibility to piping systems to absorb movement caused by thermal expansion and contraction as well as seismic movement. Custom designed to accommodate any amount of movement, Flex-C-Loops offer many advantages over traditional movement solutions. Compact Flex-C-Loops require much less space than hard pipe loops, making them ideal for indoor application where space is limited. Where as metal bellows and rubber expansion joints impose large pressure thrust forces on a piping system, Flex-C-Loops introduce zero thrust loads. Additionally Flex-C-Loops have very low spring rates compared to expansion joints. The end result is that smaller more economical anchors and fewer pipe guides are required in the system.
Flextrol can assist in calculating the amount of thermal movement in your pipe system. Call us for details about Flex-C-Loop and how it might be the best product for your application.
PTFE Smooth Bore Hose
Smooth bore braided PTFE hose is capable of carrying a wide range of difficult-to-handle media such as chemicals, steam, solvents, inks and dyes, paint, injectable materials and plastisols. It is used for a variety of applications such as sanitary transfer, bottle filling, gas analysis, extrusion presses and molding/adhesive conveying. The temperature ratings for this kind of hose are quite broad: -100ºF to 450ºF.
PTFE smooth bore hose offers improved vacuum ratings and damage resistance. It cleans easily with steam, detergent or caustic and can be autoclaved.
Available in both true bore and nominal bore.
Rubber Covered
Fluoropolymer Hose
Smooth bore fluoropolymer tube is internally bonded to multiple polyester ply cords and EPDM rubber reinforcement, then further strengthened with a high tensile strength carbon steel wire support. The EPDM rubber hose cover is ozone, abrasion and chemically resistant. While our standard color is green, this rubber cover is available in different colors which can help you identify specific process lines or trace it by department.

FDA approved
-
Temperature rating: -40ºF to 350ºF
Convoluted Fluoropolmer Hose
A convoluted fluoropolymer hose has a heavy inner wall of fluoropolymer with a stainless steel or polypropylene outer braid. The convoluted inner tubes are low profile and have a helical formed shape which promotes draining. These types of hoses are used in chemical plants, food processing and pharmaceutical companies, petrochemical sites, pulp and paper processors and general industrial companies of all types. The temperature ratings for these hoses range from -65ºF to 400ºF.
SMOOTH BORE INTERLOCK HOSE
ROUGH BORE INTERLOCK HOSE
Interlocked Metal Hose
Interlocked hose is used for specialized industrial applications and is available in different metals, sizes, and styles. Interlock is a term used with flexible metal hose meaning the hose winding is mechanically locked together and cannot come apart unless the metal is yielded. Adjacent edges are folded together to form the interlocked convolutions.
To make sure the hose is pressure tight or to minimize leakage, a packing material may be inserted into the preformed groove within the interlock.
The packing acts as a gasket seal along the entire length of the hose. Interlocked metal hose is extremely flexible and light weight. The sliding action that the hose makes is what provides the flexibility. When the convolutions on the outside of the hose are fully open, and the convolutions on the inside are fully closed, the minimum bend radius is achieved. Should the hose be forced upon its limits, it will deform permanently. Pressure tight hose is significantly less flexible because the packing material produces a greater resistance to the sliding action.
