  1. What are Benefits of Liquid Tight Jackets on Hose?

    Leave a Comment

    ANAMET Industrial Solutions applies a variety of jackets to our metal hose.

    Jacket Materials

    Our American suppliers provide us with PVC, TPE, TPU, Silicone and other materials. Custom formulations preserve liquid tight, flexible features while meeting stringent industrial demands. These jackets resist degradation in harsh environments.


    Rigorous testing, experimentation and development are ongoing. We improve safety, meet regulatory standards and exceed the target needs of industry.

    History of Success

    We have a history of supporting new technology and meeting safety standards.

    • In World War II, when the U.S. Navy asked for a liquid tight jacket on metal hose, we delivered the first liquid tight PVC jacket.
    • In 1945, our liquid tight hose, Type HTCD (high temperature shielding conduit), was installed on piston-engine airplanes to enable in-flight radio and radar for the war and afterwards.
    • In 1949, when the National Electrical Code allowed use of flexible, liquid tight metal conduit, we won Underwriters’ Laboratories (UL) listing for ANACONDA SEALTITE® with a PVC jacket on metal hose.
    • In 1963, when customers needed hose to be flexible and liquid tight in high and low temperatures, we delivered hot- and cold-resistant jackets.
    • In 1967, when customers needed hose that is resistant to oil and grease exposure, we delivered oil resistant jackets.
    • In 1980, we introduced liquid tight jackets on hose suitable for installation under raised floors for information technology.
    • In 1981, we offered a jacket that extended flexibility and protection in extreme hot and cold conditions.
    • In 1985, to prevent toxic fumes (chlorine and fluorine), we developed Halogen free jackets and avoided fluorine-based jackets on our products.
    • In 1986, we tested our jackets to make sure they met expanded industry standards for UV (sunlight) resistance.
    • In 1992, we delivered a highly flexible jacket on metal hose, Machine Tool Conduit (type MTC). This jacket provides strain relief for wires repeatedly bent to a tight radius.
    • In 2002, we delivered a low smoke, Halogen free jacket. Since then, we developed more low smoke, Halogen free options.
    • In 2013, we delivered a Food Grade hose and jacket meeting NSF requirements, which is antibacterial, easily cleaned and resistant to soap and detergent.
    • In 2023, we delivered an anti-static jacket that meets the NEN-EN-IEC 600079-0 Section 26-13 anti-static surface resistivity requirement of less than 1 billion (thousand million) Ohms.

    Color and Print Options

    Apart from meeting these safety and operational needs, we offer:

    • Color options that meet these requirements:

      • Identify safety circuits
      • Meet color code safety requirements
      • Match corporate identity colors
      • Match pleasing decor in exposed locations
    • Custom print on hose jackets deliver these options:

      • Promote brand recognition with a message
      • Mark hose with a brand name
      • Show corporate part numbers for easy identification
      • Display a safety code on the hose jacket
      • Describe acceptable use for safe installation

    Liquid Tight Fittings

    Our liquid tight jacket on metal hose supports installation of liquid tight fittings. The fitting grips the polymer jacket on a hose for a liquid tight connection.

    Our fittings have polymer seals and compressing action that fulfill industry requirements for an IP 66/67 rating. Dust and moisture are kept away from hose content.
    For more information about IP rating, see our whitepaper on the subject.

    Assistance with Hose Jackets and Requirements

    ANAMET Industrial Solutions personnel have experience delivering millions of feet of jacketed metal hose for industry worldwide.

    We are familiar with the demands of jacketed metal hose production and installation. Our customers benefit from our experience in producing flexible, liquid tight metal hose. We want to help you succeed. Please contact us if your product includes flexible metal hose.
