NAPA Gold Filters – P Seal – Tech Tip 1

Installing Spin-On Oil Filters With Molded Gaskets

Hi, I’m Mike with NAPA Filters. Today, I’m here to talk about a change in oil filter sealing technology driven by the EO manufacturers. This is a late-cut style seal. Seal we’ve used for many decades. This is a new P-style seal. Let’s get into the details.

So, we have a new gasket on the oil filters because the OE manufacturers want to protect their engines. Today’s engines have tighter tolerances. They have much lighter viscosity oils, and they want to prevent leaks.

So if there’s a problem with the oiling system, and it goes to a very high pressure, the oil filter would be the weak point, and it’s not going to leak.

This is a regular style, late-cut seal. If you take it off, imagine a rubber hose, and you’re cutting this seal, so it makes a flat surface on both sides. We’ve been using this for decades, and there’s nothing wrong with it, but the OEs attain a higher burst pressure when they take a P-style seal.

P-style, meaning I cut a cross section. It makes the letter P. It’s flat on one side. It looks like an O-ring on top. But when this is compressed, it will yield a higher burst pressure than a lathe-cut seal.

The installation is different. That’s very important. When you install a regular lathe-cut-style oil
filter with a lathe-cut-style seal, you twist it in. You lubricate it. You clean the surface. You screw it in, and once the seal touches the surface, you go 3/4 of a turn past or a turn past. You don’t screw any more than that, because if you do, the seal is going to bake on there, and then the next oil change, it’s going to be very hard to remove the oil filter.

The P-style seal doesn’t work that way. The P-style seal, once you compress the O-ring by making the can touch the housing, it protects that system with a much higher burst pressure. Let me show it to you.

So this is basically a test plate, and now I’ve got a cutaway with a P-style seal. What I’m going to do is, I’m going to lubricate my seal just like I would if I was installing it on the car. My surface is very clean here. I’m going to screw this on, but now I’m going to go way past 3/4 of a turn. You can see from the grease mark there or the oil mark that the round part of my seal is completely flat. And, you can see my can is almost touching the plate, and that’s the seal
you want to protect the system.

And the idea is once it’s installed like this, it’s not going to be any harder to remove it once the next oil change comes about. But if you only go a turn, there’s possibilities you’re going to leak. So, it’s just an installation difference, but again it protects the whole engine.

The Asian cars, Subaru, Hyundai, they’ve gone to these type seals because it protects their engine. NAPA does the same thing. We want to protect your engine. We use the same technology the OEs use.

Let’s go over some quick Tech Tips.

One, make sure you have the proper tools for the installation. Then remove the old filter.

Two, fill up the filter, and do not forget to lubricate the gasket with a small amount of clean oil. This will ensure the gasket does not bind when it meets the mating surface on the oil filter housing.

Three, clean the mating surface of any debris, and install the oil filter by spinning it onto the oil filter housing stud, just as you would any spin-on filter.

Four, unlike common spin-on oil filters with lathe-cut gaskets, a spin-on oil filter with a P-style gasket must be tightened until the metal canister appears to be touching the mating surface on the oil filter housing. And, most important, do not back it off once it is tightened.

Let’s wrap it up. If you’re doing an oil change, and installing a quality NAPA filter that has a P-style seal, make sure, for one, you have the proper tool for the installation. And two, remember to torque it all the way to where the can hits the block to make sure you get the seal compressed to avoid any kind of leakage.

We do appreciate your time. Buy NAPA quality parts, and have a great day.

NAPA Gold Filters – P Seal – Tech Tip 2

Installing Spin-On Oil Filters With Molded Gaskets

Here’s a NAPA Tech tip.

Hey, if you install NAPA Filters, you might have noticed that some of them have a different seal. The old seals were flat.

This is called a P-style seal, and it’s round on top. This seal was developed by the OEM manufacturers, and the reason it was developed is to attain a higher burst pressure.

Why do we need a higher burst pressure? Well, the engine tolerances are much tighter, and the
viscosities and oils are much lighter. Therefore, to protect the engine, they developed this seal.

The installation is almost the same as a regular seal, however once you install it, you torque it more to where the housing touches the block, and this will create the perfect installation.
