Full Replacements:

So your regulator is on it’s way to the forklift graveyard? Have no fear. Here at Intella we have a couple different models so you can find the perfect replacement to get your forklift running smooth again.

 

 

Classic model:  Impco Model J Regulator

 

The Impco Model J regulator/vaporizer delivers reliable performance and pressure output consistency. It’s reliability, especially with questionable fuel quality, has made it an industry standard for many years. Two vapor outlet pressures are available. The standard Impco Model JB (this version, meaning blue spring) provides -1.5″wc (0.37 kPa). The optional JO (J-orange) provides 0.5″ wc (0.12 wPa). The port size and mounting pad locations are identical to the Impco Cobra regulator and include a primary pressure test port and “left” or “right” fuel outlets.

Base model:  Generic Model JB Regulator

The generic model JB regulator and the Impco Model J are similar in build, although a noticeable difference would be the primer button found on the generic model JB. Impco no longer manufactures Model J’s with a primer button but the generic model JB does have one. The primer button can allow for a shot of propane  into the engine for starting purposes. The “B” stands for blue spring.  This is by far the most common model J regulator.  The blue spring offers negative 0.37 kPa (1.5 inches w.c.). The Impco Model JB diaphragm is made of hydrin and is suitable for most applications.

 

 

Repair Kits:

Don’t think you need a brand new regulator? Save some money and pick up a rebuild kit. You can repair and rebuild Model J Regulators using kits made of hydrin or silicone. You can rebuild a Model J regulator as many times as you can get your paws on a rebuild kit. Oh and you’re in luck because here at Intella, we regularly stock a few different kits.

 

What’s the difference between hydrin and silicone you ask?

Well to start off, silicone performs better in colder climates than hydrin. This is due to the fact that the silicone diaphragm stays noticeably more flexible in colder weather. The physical makeup of silicone is actually lighter than hydrin too, making a little bit more responsive. Lastly and very advantageous, is that silicone has a better resistance to being damaged from fuel.

 

 

Classic Kit: Impco Model J Repair Kit

Most common Impco regulator repair kit, mostly used on forklift propane fuel systems. Repair kit for the popular Model J forklift LPG regulator. Includes hydrin diaphragm, secondary seats, gaskets and primary diaphragm. Exactly what you need to rebuild an Impco Model J regulator.
