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.

Impco stuff you probably never knew

Impco is a manufacturer of fuel system components for alternative fuels like LPG/propane gas.  You’ll find Impco in a variety of forklift brands like Hyster, Clark, Yale, Cat, and many others.

The most popular Impco regulator is a model J.  Here’s a picture of it below.

We offer a few different versions of the model J

Model JB 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.

Model JB-2 is similiar to the JB–only difference is that the diaphragm is made of silicone and is suitable for cold climates.

We offer a generic model JB which has a primer button.    Some old models of forklifts still have a primer button on the LP regulator and we’re one of the few online that offer this version.

REBUILDING MODEL J REGULATORS:

You can repair and rebuild model J regulators using repair kits made of hydrin or silicone.    There’s no limit to how many times you can rebuild a model J regulator.

COBRA

Impco developed the next version of regulator after the model J and called it the model K.  Impco but quickly changed the name to COBRA after learning that the US trademark office would not trademark an alphabetic letter.    The COBRA will work perfectly in place of a model J.  COBRA will work for a model J application but model J should not be used for a COBRA application.

We offer COBRA repair kits and yes you can rebuild COBRA units as many times as you wish.

COMMON QUESTION:  My forklift came with a model JO.  Can I use a model JB or JB-2?    Yes–as long as you understand the difference between hydrin and silicone there’s no problem.
