Drag racing and sled pulling places huge stress on your trucks silicone hoses in a very short period of time. >PPEs hoses were designed to handle the rigors of increased pressure during racing and competition. They are equally proficient at daily driving and towing heavy loads.

Each PPE Performance Silicone Hose is strengthened with 5 plies of polyester reinforced fibers making them very tough. The Fluorocarbon lining offers better lubricity (slippery and resistant to chemicals) and the silicone rubber construction ensures that they can withstand constant boost pressures from -76 degrees all the way to plus 437 degrees Fahrenheit. In short, PPE Performance Silicone Hoses will not blow out like a stock hose will.

>PPEs Silicone Hoses are resistant to fuel, oil and chemicals while also being UV and Ozone resistant. These hoses can handle the extreme exposure that heavy usages puts upon them. With multiple sizes and configurations, there is a PPE Performance Silicone Hose for every design application.
Features:

  • 4 Inch To 3.5 Inch ID x 3 Inch Long Performance Silicone Reducer - Straight (515403503)
  • Handles high-boost pressures
  • Working pressure: 70 psi - Bar 4.8
  • Burst pressure: 207 psi - Bar 14.3

  • 6mm wall thickness 5-ply
  • Black with PPE Logo
  • Sold Individually

Note:

  • Due to the 6mm wall thickness of PPE Silicone, hose clamps must be 1/2 inch larger diameter than hose ID for proper fit

Firm and comfortable
Item Package Quantity: 2, Size: Standard
These pillows are well made. Firm, yet comfortable. I am pretty rough with my pillows. I toss and turn frequently. After one year, they are still holding up.

Quite good. I am actually surprised. Too small for queensize
Item Package Quantity: 2, Size: Queen
These pillows are actually good. After reading a ton of reviews I pulled the trigger on these. I was 100% sure I was going to receive bad quality pillows (too flat or too thick). They do take 24-48 hours to firmen up. Let's see if they flatten out in a few weeks or if they hold up. My wife said the pillow was too thick and it raised her head too much. I don't agree, I sleep perfect on these, no neck pain in the morning. Update 04/24 These are actually quite small to be considered queen pillows. They have become firm over the last few days.

Full, Fluffy & Perfectly Supportive Euro Pillows!
Item Package Quantity: 2, Size: European, Item Package Quantity: 2, Size: European
These Euro size pillow inserts are fantastic! They’re soft, full, fluffy, and hold their shape very well. The firmness is perfect — supportive without feeling too hard. They filled my pillow covers beautifully and made the bed look much more luxurious. Great quality for the price and very comfortable for lounging or sleeping. Very happy with this purchase!

amazing.
Item Package Quantity: 4, Size: Queen
WOW. I was really skeptical, but the other reviews are spot on: these are amazing firm pillows. I really hope they don't lose their firmness and become lumpy like other pillows tend to do. Excellent pillows for the price!!
