Description

Radium RADIATOR CAP, TYPE-A, 1.1BAR, BLACKThe radiator cap is an essential part of an upgraded cooling system. Radium caps are engineered to safely improve cooling efficiency by managing the boiling temperature. A higher radiator pressure effectively raises the coolant boiling point, providing an extra safety margin and preventing air pocket cavitation at the water pump. NOTE: Traditionally, "radiator" caps are mounted to the radiator but can also be found on coolant expansion tanks (below).

The radiator cap is an essential part of an upgraded cooling system. Radium caps are engineered to safely improve cooling efficiency by managing the boiling temperature.

NOTE: Traditionally, "radiator" caps are mounted to the radiator but can also be found on coolant expansion tanks (below).

Each OEM replacement radiator cap is manufactured from stamped stainless steel for durability. All 18-0076-X1X radiator caps are electroplated black.

Unlike OEM caps which use natural rubber gaskets, these radiator caps feature premium silicone sealing elements for long lasting durability.

1. 1.1Bar (16.0psi)
2. 1.3Bar (18.9psi)
3. 1.5Bar (21.8psi)

TYPES
Radium radiator caps are designed for mini size (32mm ID) radiator necks only. Available in 2 common styles (Type-A and Type-B).

Perfect to fix your Epson Ink Pad Counter Issue
Exactly what I needed! My Epson ET-4700 started displaying an 'E-11' error on the display so I learned I would have to replace the ink pad. The package came with 4 ink-pad receptacles, four baggies for discarding the old ones, plastic gloves and even a miniature screwdriver to get the backing off of the printer. The hardware part was super simple to remove the old and install the new. Hit a bit of a snag with the included software(which was a link to a website)which Windows Defender kept blocking no matter what I tried, but a quick email to support they answered right away. Sent me to a link for better software and I was able to successfully get my printer working again. A+++ transaction and service. Thanks again!

Good product-May need to troubleshoot
I am giving this product five stars even though I had issues resetting my printer because it was not product fault. The maintenance box was easy to install. Based on other reviews, I was prepared for the wic reset site that looked suspicious. I will say it is legit. I purchased a reset key which I later found out that I did not need. Read further and I will explain. After I downloaded the WIC software, I spent over 2 hours troubleshooting yrying to reset my printer. I am writing this hoping that it might help others. In the end, the problem was my Wi-Fi was not recognizing the printer. When I was trying to reset it. I ended up connecting my printer via USB cable and I was immediately able to reset my printer and start printing again. I am going to list the troubleshooting steps I took, but you might want to try that first. In addition, before purchasing a reset key, they do offer a trial key. If you have never used a trial on that printer. I suggest doing this first because in the end I used the trial rather than the key that I had purchased. Here are a few additional troubleshooting steps you could try: 1. Ensure Correct Reset Key: Double-check that the reset key you purchased is for the correct model of your printer. If it's specific to another model or region, it may not work correctly. 2. Reinstall WIC Software: Uninstall and reinstall the WIC software to make sure it's functioning properly. Sometimes a corrupted installation can cause errors. 3. Run the Software as Administrator: Make sure you are running the WIC software as an administrator. Right-click on the WIC Reset tool icon and choose "Run as Administrator." 4. Disable Firewall/Antivirus Temporarily: Your firewall or antivirus software may be interfering with the connection. Temporarily disable them and try again to see if that helps. Make sure to turn it back on when finished. 5. Try a Different USB Port: If you are connecting via USB, try switching to another port. Alternatively, if you're using Wi-Fi, you might want to try a USB connection to see if that helps the software communicate with the printer. This is what worked for me. 6. Use a Different Computer: If possible, try using the reset software and key on a different computer. Sometimes system-specific issues can interfere with communication between the software and the printer. 7. Check for Firmware Updates: Ensure that your printer's firmware is up to date. If it's outdated, it might cause incompatibility with the reset tool. Be cautious, as some updates can prevent third-party reset tools from working. If none of the above works, it might be worth contacting the vendor of the reset key. They may have specific guidance or offer a replacement key if the one you purchased is faulty. Last resort would probably be to call Epson.

Perfect for my Epson 2720!
When my Epson 2720 printer pooped out on me and said my ink waste box was full, I was so sad. After watching a billion YouTube videos, I learned there are a ton of people selling new ink boxes and I had no clue which one to pick. I am the most electronically illiterate person on the planet so I just knew it wouldn't be easy for me to fix... wrong! This kit came with the new ink waste box, tools to change it out, a bag to throw the ink filled box into, instructions, and an extra pad for next time. After removing the old box, the new one slid in perfectly. Resetting the wic code was extremely easy as well! The instructions show step by step diagrams on what to do. It was a fast and simple process. It all worked out too well for me (normally it's a domino effect of chaos when I repair something) so the first print to see if it all worked was a nail biter. It printed beautifully! If you have a 2720 that needs repaired, this is the product for you!
