Type MPR: Moisture Resistant Box This design has a moisture resistant die cast aluminum box with a non-removable polyurethane gasket in the lid. Lid is secured with captive stainless steel screws. Body and lid are painted in basic industrial gray; interior contains copper ground screw. Box is mounted to a plate that is brazed to the element. Available in a wide variety of sizes. Type K United States, Canada, Mexico: Chromel®/Alumel, Temperature Range: 32-2282°F (0-1250°C) 100 Fitting and Leads Type J United States, Canada, Mexico: Iron/Constantan, Temperature Range: 32-1382°F (0-750°C) Type HS: Hi-Seal Fittings Hi-seal brass fittings are highly dependable under the most adverse conditions. For reliable and trouble-free service with ease of installation, we strongly recommend hi-seal fittings. Available for 3/8″ and 1/2″ diameter tubing. Male thread is 1/2″ NPT for 1/2″ tube and 3/8″ tube. Cooling/Flow Tube Fittings Type FF: Flared Seal Fittings Brass flared seal fittings are well adapted for low to medium pressure and resistant to mechanical pullout. Available for 3/8″ and 1/2″ diameter tubing with SAE 45° flare. Type EP: Explosion & Moisture Resistant Box Cast iron explosion and moisture resistant boxes should be used in areas where the surrounding air may become contaminated with combustible gases or a high humidity level may exist. Installation requires one box per Cast-In Heater half and they are brazed to the tubular heater. The standard box has one 1/2″ NPT hub. Optional: Two hubs per box available. Cast-In Heater fitted with boxes can be factory prewired with high temperature lead wire, protected with special armor cable. If either of these options is required, please specify the following: Number of hubs Cable type Lead wire length Cable length Type CN: NPT Fitting A double threaded pipe fitting is attached to the end of a cartridge heater to allow for installation into a threaded hole. Brass fittings are silver brazed and stainless steel fittings are heli-arc welded. Type C2: Standard Terminal Box (on flat pad) Type C2 is an individual terminal box for protecting the terminals on each Cast-In Band Heater half and on many other Cast-In Heater designs with one set of heater terminals. The C2 box design requires a flat pad on half-round castings or a flat surface on other casting designs for mounting. It is made from heavy gauge, rust-resistant sheet metal. The cover is removable for easy access to terminals. The box has two 7/8″ diameter knockouts opposite each other for standard 1/2″ BX connectors. To simplify installation, Cast-In Heaters fitted with boxes can be factory pre-wired with high temperature lead wire that can be protected with armor cable. If one of these options is required, specify terminal box type, lead wire and cable length. Satisfies NEMA 1 requirements. Standard C2 box size: L = 4″ W = 2-1/2″ H = 2-1/8″ Style 2: Armor Cable Adjustable Bayonet Thermocouple Design Features Insertion length adjustable over length of armor cable.
