Accessories

Swivel Adaptor

Part Number: ACSWA
Hose Master’s plated swivel adapter converts the integral hex male to a swivel end. This unique adapter creates a positive metal-to-metal seal when used with Hose Master’s exclusive 30° chamfered hex male fitting. This swivel adapter facilitates installation and is only compatible with Hose Master’s FireShield or FireShield QuickClamp connectors.

 

Anode

Part Number: ACANO
Hose Master’s underground connectors, used with our anode, comply with EPA regulations for buried metal components. Our easily monitored system also meets NACE RP-01-69 standards for cathodic protection.

FireShield QuickClamp assemblies make tight flex connector installations as easy as possible. Offered with a multitude of end connections (including FRP fittings) and custom hose lengths, FireShield QuickClamp assemblies offer installers the ability to fasten one or both ends of a connector within a piping system with minimal use of tools – eliminating timely labor costs and increasing profits.

  • 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.
