Hose Master’s FireShield connectors are the safest, longest lasting, and most flexible metal hose connectors manufactured today. Hose Master’s unique process makes the difference by minimizing residual stress points created in the hose during the manufacturing process. Hose Master’s proprietary tube seam weld technology resists aromatic vapor permeation and Hose Master’s precise ASME certified welders follow specified procedures to insure the strongest fitting attachments.

Hose Master’s extensive array of available end fittings offer the quickest and most cost-effective solutions for connecting fiberglass or flexible pipe to the submersible pump and shear valve. Hose Master’s FireShield connectors minimize threaded connections, which means fewer leak points and reduced installation time and labor.

Hose Master’s FireShield connectors meet all specifications for aboveground and underground piping applications, and comply with NFPA and UFC codes. They are rated for full vacuum and are available with BSPP and BSPT threaded fittings. Connectors are designed to accept approved secondary containment systems.

  • DO design the installation to allow for all movement (ground, vibration, etc.) after the installation.
  • DO keep the hose free from all objects and debris.
  • DO measure to ensure proper length of connector has been selected.
  • DO handle and store the connectors carefully before an installation.
  • DO follow all printed instructions included with the connectors.
  • DO note the minimum bend radius as specified.
  • DO install flexible connectors so that the bend is as close to the center of the connector as possible.
  • DO keep the painted lay line straight and on the centerline of the connector.
  • DO use a wrench only on the hex flats.
  • DO use the manufacturer’s recommended cathodic protection system or dielectric isolation boot.
  • DO check for leaks before covering the installation.
  • DON’T use a wrench or any other tool on the hose or braid collar.
  • DON’T twist or torque the flex connector.
  • DON’T over-bend a flexible connector beyond its minimum bend radius.
  • DON’T install a flexible connector with the bend next to the end fittings.
  • DON’T attempt to stretch or compress a flexible connector to fit an installation, or allow connector to stretch or compress during use.
  • DON’T restrict flexibility by allowing a connector to come into contact with other components or equipment during an installation or during use.
  • DON’T expose connector to damage or corrosives during storage, installation or use. Groundwater, road salt, soil, etc. are or may contain corrosives. If necessary use a cover or boot to protect the connector.
  • DON’T attempt to reuse a flex connector once it has been installed.
