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.
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.
There are many conflicting articles and posts online about original OEM forklift parts and aftermarket forklift parts. For the record, everything we sell at Intella Liftparts is aftermarket.
But what is aftermarket? Is it the same as will-fit? Knock-off?
Let’s get some terms out of the way. First off, we define aftermarket forklift parts as any forklift part that doesn’t come packaged in an OEM box from an OEM dealer. Now many OEM dealers will state the party line that all aftermarket parts are bad. The only problem with that logic when it comes to Intella, is that we buy from many of the same suppliers than forklift manufacturers buy from. We supply Donaldson filters, Axletech axle parts, Dana transmission parts, Perkins engine parts…you get the picture. We try to buy parts direct from the same supplier that supplies the OEM. Most times we can do that–sometimes we cannot.
We take the original part, make a drawing from it and then from that drawing we manufacture the part. Our manufacturing division, Inparts BV, often makes many of the machined parts and forklift cylinders which we offer.
Is using aftermarket forklift parts bad? Sometimes you don’t have a choice. Sometimes aftermarket forklift parts suppliers can supply a part that even the OEM can no longer supply. In those cases you don’t have a choice. But more important than the sticker on the box is the part itself and the company supporting the parts. You can be assured that we stand behind everything that we sell!
An open secret in the industry is that most of the large OEMs supply aftermarket parts as well as OEM parts. Toyota’s StarLift program is mostly TotalSource forklift parts. Hyster’s Unisource program? Yep, supplied by TVH. In other words, OEMs act like this: for parts on our brand forklift, you need to buy our OEM parts . But if it’s any other brand, feel free to use our competitive parts program. Which is, um, aftermarket.
