Used for high to low viscosity oils, asphalt, tar, wax, molten salt, heat transfer liquid media and other compatible solutions.

Type B - Bulkhead Fittings

Bulkhead fittings provide a leakproof method for mounting tubular heating elements through tank walls. Standard are round brass fittings crimped onto the element that are suitable for low pressure water (up to 80 psig) and non-pressure air. A brass hex nut, plated steel washer and gasket are supplied as standard.

Type MC - Mounting Collar

Plated steel mounting collars are locked in place with a set-screw and serve as an adjustable stop for through-the-wall mounting. Collars are shipped in bulk unless otherwise specified. Mounting collars can be ordered with the heater or purchased separately.ting collars are locked in place with a set-screw and serve as an adjustable stop for through-the-wall mounting.

Type LR - Locator Washer

Locator washers are permanently attached to the heater sheath by staking/crimping and are used to limit the movement of the heater while allowing for expansion and contraction of the heater sheath.

Type MF - Mounting Bracket

An economical way to mount the heater in non-pressurizing, non-liquid applications.
