HPS Performance Stainless Steel T-Bolt Hose Clamp Size # 60, fit 2.5" ID hose SSTC-70-78 Polish 2.76"-3.07" (70mm-78mm)

Quality product, great value. A great way to dress up your engine bay and make it look more like a race car. These are wider than normal worm clamps, so will spread the load better for silicone. These clamps require far less torque to tighten due to the smooth action of the nut and bushing, so be careful not to over-torque. Hose size in description refers to nominal hose ID for standard intercooler couplers. I used the HPS 2.75" intercooler couplers, and they fit perfectly. 70-78mm refers to OD range - 78mm being absolute max (clamp will barely fit over 3.1" OD).

Turbo outlet clamp works good and held 40# of boost with no leaks.

I will admit that I could have read the description several times more to make sure BUT this item is poorly described. I bought this to fit a 2.75 inch throttle body and it does not. The dimensions described seem to say that it is for 2.75 to just over three inches but this is only slightly bigger than the 2.5 inch clamps I already own. The actual clamp fits inside diameters not outside. The item is well made, no quality problems here at all.

With the locknut minimally engaged the inner diameter is only 76mm

Clamps work but are a one time use. The washer under the nut is thin and bends into the threads ruining it. Good for mocking up but definitely not as a permanent clamp

these two clamps i got the spot welds didnt hold the first one poped while tightening and the second one poped on the test drive not good

We used this clamp to secure sails in our back yard. Great product, will buy again.

Used this clamp to secure an intercooler hose on a GTR after the other one blew off on the highway at high PSI. Served a purpose and still going strong!

Perfect

Excellent quality

Very strong clamp, I only use HPS clamps on all my turbocharged vehicles. Including my duramax with 35psi of boost!

good
