Description

1777CW 1963-1974 Inline 6 CW Rotation Riser 3 7/8" water pumpIf you are running a v belt with a riser set up (like a zips riser) and find you have heat cycling it might mean trapped air. The best solution is to build pressure to and the best tool is pump 1777CW. We designed an impeller with an increased vane count and a reduced impeller vane clearance to take build that pressure. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II

If you are running a v belt with a riser set-up (like a zips riser) and find you have heat cycling it might mean trapped air.  The best solution is to build pressure to and the best tool is pump 1777CW.  We designed an impeller with an increased vane count and a reduced impeller vane clearance to take build that pressure.  It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

We developed this hi flow pump because trapped air can cause overheating in slow speed situation and stop and go traffic. It has been proven time and time again that reducing the cycle time between the heat source and the heat sink drops engine temperatures. It has been reported that people who run the heater line to the port between No. 6 and No.8 heads and not the manifold seem to have better luck freeing the air.

Picture is misleading
Color: RYLCC-BLK
Great product! Good quality! The picture of the product is a little misleading as it looks like there are 2 tubes instead of one.

Perfect sized wrist-rest!
Size: Compact, Size: Compact
Great wrist-rest! Very squishy and feels comfortable & cool even after hours at the computer. The rubber gripper bottom is effective & it never shifts around for me. Also, love that it fits the length of my 75% keyboard & my boyfriends 60% Wooting 60HE keyboard perfectly

Very Pleased!

Review for: Cooling Gel Wrist Rest Pad -Full Size 18"- Memory Foam Palm Rest with Non-Slip Footpad - Ergonomic Design Wrist Support - Desk Keyboard Accessory Gaming Gear (Large-Full Size). I've had this for a week and I'm impressed! There is no skimping on quality, which is rare nowadays. It is made extremely well, solid yet soft. I love the feel of the outer cover. It's comfortable and stays in place. And let me add... I'm putting it to the test. I have a rolling over-bed/couch desk. It has a raised 1/4" lip around the top. I put this wrist-rest on top of that lip. So far there's not any wear across the bottom of this wrist-rest. And that's with me using it for my wrists... and my elbows. It far surpasses the last rest I bought. From my experience, many sellers slap the phrase "memory foam" on their products when they are not. That's NOT the case here. This rest immediately bounces back to its original shape. It's true memory foam! It's so comfortable that I forget it's there yet I enjoy the comfort immensely. Also, it has no smell. ***From my experience so far... I highly recommend this product!

Comfortable and functional, but beware of cardboard/mdf insert
Size: Compact
I’ve been using this wrist rest for a bit now, and for the most part, it does exactly what it’s supposed to do. It provides a comfortable amount of support for my wrists during long typing sessions, and the cooling gel aspect is definitely a nice touch that adds to the overall comfort. That said, there are a couple of drawbacks to keep in mind. The surface seems to attract dirt and grime pretty quickly, so you’ll need to wipe it down often to keep it looking clean. More importantly, the build quality of the base is disappointing. I believe its a cardboard inserted into the bottom, which snapped very easily when I was just barely bending it while cleaning it. It’s a shame because the rest of the product is great, but I really wish they had used a more rigid, durable material for the bottom instead of whatever this cardboard/mdf is. This is why I’m giving it 4 stars.
