About this part

The Bykski CC-UQD4-X is a stainless steel quick connector with a built-in stop valve, designed for server, data center and PC liquid cooling loops. It is for builders who want to connect and disconnect part of a loop without draining it. It has a G1/4 thread, so it fits any G1/4 port.

A quick connector lets you separate a section of the loop for maintenance or upgrades, and the stop valve closes the line as you disconnect it. Stainless steel construction makes it a durable connector for systems that are serviced often. It installs by hand, with no tools needed.

What buyers said

Left by people who bought this part here. Compatibility reports are the useful ones — if you installed it, say which board.

Before you install it

This is a component, not an assembly — how it goes in depends on the loop it is joining. What does not change is the last step: leak test before power. Run the pump on a bench supply with the rest of the system unpowered. 24 hours is the standard, an hour is the minimum.

Custom water cooling is installed by you, at your own risk. We are not responsible for leaks, or for damage to your parts or system. If you're unsure at any step, ask before you power the loop.

This part is specified by what it connects to, not by a card model:

ONLY Compatible with:

Any G1/4 port

Check those against your build before you order. If anything does not match, ask us first — it is cheaper than a return. Part number CC-UQD4-X.

Is it in stock, and when will it ship?

Not currently available to order, and we have no ETA to give at this time. Ask us and we will confirm one in writing as soon as we have it.

Can I return it if it turns out not to fit?

Yes. Returns are accepted within 30 days and are easy to start in the support center. Unopened items can be returned for store credit with no restocking fee; other returns carry a restocking fee, higher for items that have been installed or used. So we would rather check the fit with you first: send us the model and we will check it against this part.

Will I pay import duties or customs charges on delivery?

Not on a US order. US import duties and tariffs are already included in the price, so nothing is collected at the door and there is no brokerage fee. Orders shipped outside the US may owe that country's customs fees and duties.

Who handles the warranty?

BYKSKI.US, the exclusive US distributor, from Boise, Idaho. Claims are handled domestically rather than returned to an overseas factory. Installation is at your own risk: we are not responsible for leaks or damage to other hardware.

Is shipping free?

Shipping is free on orders over $125 to addresses in the lower 48 US states.

Are printed instructions included?

No printed manual is included. Installation references are in the product gallery images, and the install guides on this site cover the process step by step.

Do I need anything else to use it?

Check the parts list above against what you already have. If you are building a loop from scratch, send us the full parts list and we will tell you what is missing before you order.

Ask us before you order

Send your exact hardware model or ask for an ETA on this part and we'll confirm the right part before you spend $54.99 — or tell you honestly that this isn't the one.

Returns are accepted within 30 days and are easy to start in the support center. Unopened items can be returned for store credit with no restocking fee; other returns carry a restocking fee, higher for items that have been installed or used.
