Corrugated Hose (Braided/Unbraided)


Corrugated Metal Hose is generally used for flexing and vibration, while conveying liquids and gases. The metal wire braid provides the assembly with a higher pressure capability by acting as a restraint against hose elongation and acts to dampen vibration. The annular hose is formed from tubing into individual parallel corrugations and the braid is manufactured by grouping single wires and then braiding them into an intricate pattern that tightens when the braid is stretched. Alloys include bronze, steel, stainless steel, and Monel. Working pressures range from full vacuum through 12,000 psi. Temperatures up to 1500°F. Standard sizes range from 1/4" through 18" I.D. A variety of size, length and end fitting configurations are available.
Flex Connectors

Flex Connectors


Flex Connectors are primarily designed for installation in pump suction and discharge lines, to prevent damage to equipment caused by vibration and pipe misalignment. The flex connectors are hose assemblies manufactured from braided corrugated metal hose and are available in bronze, stainless steel and Monel. Flex connectors are available with a smooth bore PTFE liner.

End fittings include flanges, MPT and sweat. Working pressures range from full vacuum through 12,000 psi. Temperatures up to 1500 °F. Standard sizes range from 1/4 in through 18 in Inner Diameter. A variety of size, length and end fitting configurations are available. Standard and special assemblies are available and built to customer specifications.
Bronze Braided Connectors

Bronze Braided Connectors


Bronze Braided Connectors are generally used to absorb vibration in air conditioning and refrigeration piping systems and for the elimination of piping stress on pumps. They are constructed of bronze or stainless steel corrugated hose and braid. End fittings include copper female sweats, MPT, FPT, and flanges. Working pressures up to 400 psi at 68 ºF. Standard sizes range from 1/4 in through 4 in Inner Diameter. A variety of size, length and end fitting configurations are available.

Stripwound/Interlock Hose


Stripwound/Interlock Hose is generally used for conveying saw dust, grain, plastic pellets, tar and asphalt, and exhaust fumes. The hose can also be used as a protective armor guard on other types of hose assemblies. The hose is manufactured by spirally winding a preformed continuous metal strip, so that the edges interlock to form a hose. The stripwound/interlock hose is available with a directional flow liner. Alloys include galvanized and stainless steel. Standard sizes range from 5/32" through 24" I.D. A variety of size, length and end fitting configurations are available.

Jacketed Hose Assemblies


Jacketed Hose Assemblies are generally used to heat fluids, which are normally viscous at 70°F. Assemblies use the jacketed section to carry steam or hot oil, to raise the temperature of the fluid moved in the internal hose, thereby lowering the viscosity and permitting uninterrupted material flow. Jacketed hose assemblies are made up of two flexible hose units, one inside another. Reference Corrugated Metal Hose. Alloys include bronze, steel, stainless steel, and Monel. Working pressures are per application. Temperatures up to 1500°F. A variety of size, length and end fitting configurations are available.

Tar & Asphalt Hose


Tar and Asphalt Hose is generally used for road repair, spray and patch work, and transfer of tar and asphalt. These assemblies use a heavy weight interlock/stripwound hose, made from galvanized steel strip, with high temperature packing. Working pressures up to 35 psi. Temperatures up to +450°F. End fittings include MPT and FPT swivels. Lengths up to 60'.
