These Tech sessions are great, thank you for taking the time to enlighten and educate your customers.

I had these rings installed on my CRF450r by a shop in Phoenix (Cycle Dynamics) the owner is the grandson of the founder of Total Seal. I got 54hrs on OEM top end before it started having excessive oil blow bye. The bike has 121hrs on it now & still runs like a top. I can't rightfully attribute the longevity difference solely on the rings since new piston, valves, seats & head machining were also done but they do work & I have no problem using them again.

I have used gapless in my track day motor, they work great. They were easy to understand and install. Uh only the 2nd / middle ring - price was a factor, but followed this idea from a more experienced engine builder.

They are always my first choose. HAVE USED THESE RINGS SINCE THE EARLY 70's never a failure .

excellent! thank you

2nd ring typically 4.5/" . Go big on top for the extra heat .007ish? Working with 5 9 cummins for salt flat racing.

Do you guys make gap-less rings for the 6.5 Turbo Diesel? Where do I get it?

good for subaru turbo`s - power to the crank - pass it on !

Would try claimer gapless rings do well in a street motor

Why don't you just make it a single piece ring with a L shaped lip on both ends to eliminate the gap.

Im from Germany, I have a 1970 Corvette LT1 w. stock 350 SB engine now 4.030 overdrilled and honed, using new TRW 1970s OEM style forged pistons on pink forged GM rods...I found one of your older gapless street performance kits that uses the second gapless ring system. This older Total Seal Ring kit was made 1995. Would you still suggest using it (I have it here on my desk) or better the newer Kits with gapless top ring?

Test thes rings 1992 with Nos System 250 hk.No broblem SCB 356 happy Engine..in the 10 sek Street car....

QUESTION ,THERE NEEDS TO BE BLOW BY IN THE CYLINDER OTHERWISE YOU RUN INTO RING CHATTER NOT SO ? SECONDLY YOU ALSO MAKE LOWER TENTION RINGS ,IS THAT NOT THE SAME THING AS A WORN-OUT RING I MEAN WORN-OUT RINGS ALSO LOSE TENTION

Why not just a simple rebated overlapping ring. Having two rings seems complex.

I am very interested in gapless rings. I heard that the rings themselves wear much faster in a daily driver application. Is that true? If they do wear faster, how much are we talking? I'm currently running a centrifugal supercharged 355 sbc at 9lbs. Roller cam/aftermarket heads about 650hp. Would you suggest a gapless top or a gapless second ring? Is running both overkill and unnecessary? Thanks for any info you can provide. I've loved the idea forever but I have no personal experience with gapless rings.

👍👍👍👍👍👍👍😎😎🇺🇸

Gapless rings are made of gold, not because of metallurgy but because of profits.

This isn't magic linking rings I was hoping for 😑

Gapless piston ring will cause catastrophic damage to the ring itself together with pistons and cylinder walls its very impossible to make it last long specially with diesel engines

The only ring I will run. It will also increase fuel efficiency by 2 to 5 %. Why? If you have say 4% blowby, (very realistic #) that means that 4% of your fuel is being wasted. 4% is Alot of fuel over the lifetime of a street engine.

Negative to total seal gapless rings? Cost... lol.

I know, people talk so much bullshit about engines and cars it is scary sometimes. And all of it is just superstition. No bases in science or reality. Who comes up with that shit???

You cant run gapless rings in a 4stroke combustion engine

Let’s stop kidding ourselves hear,their is No Such thing as a Gapless Piston Ring,to be Gapless it would have to be a Solid Ring which if it was you would Not be able to get it over the Piston and into the ring groove. Having no ring Gap wouldn’t work anyway because the engine would seize up when it got to operating temperature,each of these ring Must have a gap,one to get them over the piston and two to allow for expansion and lubrication because without oil getting to the Pistons and Rings the engine would be knackered in no time. When fitting ordinary Pistons and Rings you all supposed to turn the rings around the pistons so that the gaps Don’t lineup thus preventing blow by or compression loss. I’ve been building engines for over 50 years and I wouldn’t think using this type of ring idea would do anything for longevity of a cylinder bore due to poor lubrication at the top of the cylinder. I honestly think this is a Snake Oil type of operation don’t fall for it. A firm called Cord Piston Rings did a similar thing years ago to stop oil consumption in a worn engine and they only worked for a short while and then the engine had to be stripped and rebored and new Oversized Pistons fitted.
