Compatible with SPA Super A, with 1.5mm / 1.5mm and 2mm channels.
Ring thickness:
1st ring 1.5mm - Made of carbon steel, which is 35% more resistant than cast iron and on average 30% lighter. With DLC (Diamond-Like Carbon) treatment, which is the application of carbon particles, whose physical and chemical properties are very close to those of the diamond, providing greater resistance to the material and reducing the friction of the surface, which significantly reduces friction when working against other surfaces.
2nd ring 1.5mm - Made of cast iron.
3rd ring 2.0mm - Manufactured in 3 pieces, which guarantees easy maintenance, better stability in the control of the oil film and improves the oil removal through the piston lubrication holes, as it has a better area for displacing this oil.

About CMD Extreme Pressure lubricants:

When the operation requires extreme pressure, all ordinary lubricants break down and allow metal-to-metal contact with consequent scoring, frictional heat, work and cutting tool damage.
They will not corrode the finest surfaces nor will they mulsify with cooling liquids. But these facts are not the most remarkable feature of CMD lubricants. The truly outstanding property of CMD is its ability to withstand extreme pressures!
CMD EXTREME PRESSURE lubricants are regularly used from 40,000 to 50,000 psi.

        Durable and a Favorite!
        Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large, Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
        I *was* gonna hide them for a later date because they are great for keeping them busy and quiet! But the Amazon box got delivered and my Pittie, Whiskey, was very excited about it... that girl's got a great nose! Through a cardboard box, a sealed bag, and shrink wrap, she knew the best filled bones were in there! She chose the beef one. Otto, my Heinz-57, chose the peanut butter. The bacon and cheese will act as mediator so when they steal and switch, there's always a 3rd bone to keep the peace. These Pawstruck bones don't splinter like the Ol' Roy ones from Walmart (see photo, Ol' Roy is the darker one). Sure, they can manage to break off a few dull, tiny bone chips, but nothing that will hurt them, even if swallowed. Which, in a way is good; hard to break teeth if the bone gives just right. Whiskey is a mega power chewer and can destroy just about anything, but these hold up quite well and don't cause any gastrointestinal upset. The dogs absolutely love them! I also never notice any smell or any significant mess. Very heavy duty and thick, great large size so they really have to work on them. I also like the filling ingredients much better than the corn meal and various fats seen in others.

        4 Paws up! My dogs LOVE them
        Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large, Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
        I have 2 large dogs who LOVE THESE. A Great Pyrenees mix who’s a skinny 80lbs and a lab/terrier mix who’s a chunky 50lbs. They both love bones and can REALLY chew through them quickly so I’m really picky about what I buy them. Here is what is important to me and how I rate and choose bones. These are my comments on this bone set specifically: Do they break/splinter? -They don’t splinter, I have seen smaller pieces that have broken off and when the bone gets down to the end (but this is normal with bones) at which point those pieces can be thrown away. I have never had an issue with them choking, being too small or hurting my dogs though and they are aggressive chewers so I could see this happening with some dogs and never happening with others. 4/5 stars for this. Do they smell/leave stains on the carpet? -Nope! No odor and they actually leave my dogs breath smelling better and their teeth cleaner! 5/5 stars Does it upset my dog’s stomach? (My bigger guy can’t tolerate a LOT of things, he vomits often and also gets diarrhea if he eats the “wrong” thing so I have to be very cautious.) -NOT at all! No upset tummies. This is always very, very important to me. Make sure you have lots of water nearby for your pups though, these will make them very thirsty. 5/5 stars Do they hurt my dogs tongue, mouth or teeth? -Nope, no issues with this. They’re able to gnaw into these aggressively without hurting themselves. 5/5 stars Are they gone in 2 seconds? -No! I’m always worried the “stuffed” bones will be left in the dust after the stuffing is all gone but my dogs will still keep chewing on these after the stuffing is gone. They still enjoy the bones and they last for quite some time, weeks at minimum. I can also stick some peanut butter or other treats back in the middle after they get the original stuffing all out of them to “reuse” them if it seems like they’re getting a little bored with them. 5/5 stars Do my dogs ACTUALLY LIKE THEM? -They love them. 5/5 stars Price? -Great and totally affordable. $20 for 3 of them.. so less than $7/bone. This is comparable to a bone from the pet store and these last a lot longer than something you would find there in the “fresh” grocery-store-like-section of the pet stores. I’m an avid review reader, especially when it comes to items for my fur babies because I want the best for them. I truly love these bones and will keep buying them. I will continue to buy these!

        ⭐️⭐️⭐️⭐️ Finally Found a Long-Lasting Bone That Actually Keeps My Dog Busy
        Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
        I’ve tried a lot of filled bones and chew treats over the years, and most fall into two categories: gone in 5 minutes, or upset stomach later. These filled beef shank bones hit the sweet spot. The bone itself is thick, dense, and real, not a thin, brittle shell. My medium-large dog is an aggressive chewer, and this keeps him occupied for a solid 30–45 minutes working on the filling, then even longer gnawing on the bone afterward. The filling smells fresh and appetizing (not rancid or overly greasy), and my dog goes crazy for it. We’ve tried the cheese-style and peanut butter–style fillings, and both were a big hit. No crumbly mess, no weird residue, and no digestive issues so far. What I really appreciate is that these feel safer than many cheaper alternatives. The edges don’t splinter, and the bone wears down gradually instead of cracking. Why I’ll keep buying these: • Long-lasting even for power chewers • Real beef shank bone, not pressed junk • Filling dogs actually care about • Helps with boredom and anxiety • Good value compared to pet store brands Minor cons: • Can get a little smelly after heavy chewing • I supervise and take it away when it gets small (as with any bone) If you’re tired of wasting money on chews that disappear in minutes, these are a fantastic upgrade. My dog is obsessed, and I finally feel good about what I’m giving him.

        Best bones out there
        Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
        These are the best bones I’ve ever bought. I have a lab puppy and as you can imagine most bones don’t last long around here, but this one keeps him entertained for days.
