Description

Acuity 3.5" ID Velocity StackSpun from 5052 aluminum to a parabolic profile, this velocity stack is a great way to adapt a filter with 6" (152mm) opening to a 3. 5" tube or to simply reduce inlet losses on a 3. 5" (89mm) tube or turbo inlet. Often, spun velocity stacks don't feature beads to help retain filters, leading to poor filter fitment. And with its 1. 3mm (0. 05") wall thickness, it's perfect for welding to industry standard 0. 060" wall aluminum tubing if making a custom

Spun from 5052 aluminum to a parabolic profile, this velocity stack is a great way to adapt a filter with 6" (152mm) opening to a 3.5" tube or to simply reduce inlet losses on a 3.5" (89mm) tube or turbo inlet. Often, spun velocity stacks don't feature beads to help retain filters, leading to poor filter fitment. And with its 1.3mm (0.05") wall thickness, it's perfect for welding to industry-standard 0.060"-wall aluminum tubing if making a custom intake setup. ACUiTY's velocity stacks feature a rolled bead on the large end and a flared outlet on the small end to make sure your filter and coupler stay attached. Additionally, a durable, matte black, painted coating is applied to each velocity stack for corrosion protection.

    Sturdy and holding up so far!
    Size: Small 15", Style: 3 Knot, Pattern Name: Dog
    This is a quality pull toy that my Yorkie ("Finnegan") loves. It is holding together well as my dog can be a maniac at times. Moderate chewing has not hurt this toy. I do not buy toys with squeakers in them as they worry me. Finn entertains himself and then brings toy to me for a tug of war. I recommend this item. Good bang for the buck!

    EXCELLENT QUALITY
    Size: Medium 20", Style: 3 Knot, Pattern Name: Dog
    I have a German Shepherd/Pointer mix who is 10 months old. He has been in the throes of teething and destructive exploration. He's chewed up clothing and shoes. He chewed a hole in our couch and one in our brand new mattress (He was never left home alone until this point but as my mother came to visit and my boyfriend was back at work, I had no choice but to trust him alone for about an hour a day for 3 or 4 days... he clearly didn't earn that trust). He loves ropes because he can gnaw them, whip them around, and play tug of war or fetch with them at any given time. We love ropes because they keep him occupied and relieve his desire to chew things. Unfortunately, he was destroying rope after rope after rope. Some ropes were worrisome because they would quickly start fraying and falling apart. We would have to help remove strings he has swallowed from his behind while he was out doing his business... My boyfriend's mother picked up a Mammoth TireBiter tire and rope toy for him but it was much too small. Still, he loved it and it stood up very well to his chompers despite being way too small/weak for him. Looking for a larger version of the Mammoth TireBiters, I stumbled across this rope toy and gave it a shot. Let me tell you, I don't think I will ever buy rope toys from any other brand! We have had this rope for over a month and it is still going strong. It does show some small signs of wear and tear but you would swear we bought it last week. It is very strong and durable. It has held up through many long gnawing sessions. It has been put through countless hours of fetch and tug of war with no signs of giving out any time soon. I am so in love with this rope and so is my pup!

    Only for tug-a-war play.
    Size: Small 15", Style: 3 Knot, Pattern Name: Dog, Size: Small 15", Style: 3 Knot, Pattern Name: Dog
    This should only be advertised as a tug-a-war dog toy. I gave the toy to our 6 month old puppy and in, not even, an hour it was ripped apart. He’s not big enough for the larger ones yet. Not sure if I’ll try the next size larger.
