Specifications: Color: black Material: copper Size: as shown in the picture Package includes: 10 x Plug fitting with o-ring Review: It is a plug - These are very nice. The head is somewhat thick, enough to screw on with your fingers so be aware of that. Makes them really easy to install. Threads went in perfectly and had 0 fitment issues on all 10. Great value Review: These caps work ALMOST, everywhere.. - My Pic is of the top of my EK reservoir. You'll notice that I have the stock nickel plugs on top and the front side. If you look closely, you'll see that the top plugs are slightly recessed into the top itself where the front plugs are not. In those recessed ports which only exist on the top of EK reservoirs, are just about the only place these new black plugs won't fit. The head on them are to wide to go down in the recessed cutout so they will not seal. Other than that, they work great for my EK GPU waterblock and elsewhere in the loop. I was really hoping to get rid of all of the nickel colored stock EK plugs. I suppose I could add an extra o-ring or two to the top plugs in an effort to make contact with the recessed area better. This of course is not the fault of the plug design. It's just EK being EK and making custom stuff so you buy from them for accessories. These are actually really good quality of the price. They have a nice smooth black finish and are pretty beefy. They don't feel cheap at all. ## Features - Package includes: you will get 10 pieces of water cooling plug fittings, each plug contains a rubber sealing ring, you can use it in your computer water cooling system; Sufficient quantity can meet you demands and replacement - Good tightness: the water stop plug is equipped with o-ring rubber gaskets, which provide nice air tightness, which can prevent internal liquid leakage and oxidation and prevent dust from entering the liquid cooling device - Reliable materials: the G 1/4 plug fitting is made of quality copper, and the surface is -plated, which are rustproof or corrosion-proof, can serve you for a long time - Thoughtful design: the PC cooling plug is designed with a minus groove design and non-slip texture on the surface, no tools are needed, and the installation can be completed by simple tightening by hand, which provides you with convenience - Apply to: this black stop plug fitting with a size of G 1/4 inch, the diameter of it is 18 mm, suitable for computer water cooling system applications; After being covered, it can store the liquid in the water cooling system for a long time ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08TTRM5QH | | Best Sellers Rank | #78 in Water Cooling Systems | | Brand Name | Hotop | | Compatible Devices | Desktop | | Cooling Method | Liquid | | Customer Reviews | 4.8 4.8 out of 5 stars (287) | | Manufacturer | Hotop | | Material Type | Copper, Rubber | | Noise Level | 0.1 Decibels | ## Product Details - **Brand:** Hotop - **Compatible Devices:** Desktop - **Cooling Method:** Liquid - **Manufacturer:** Hotop - **Material:** Copper, Rubber - **Noise Level:** 0.1 Decibels - **Number of Items:** 10 ## Images ![10 Pcs Black G 1/4 PC Water Cooling Plug Fittings with O- Ring Stop Fitting for Computer Water Cooling System - Image 1](https://m.media-amazon.com/images/I/81PKlr4T9TL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It is a plug *by A***R on January 8, 2026* These are very nice.
