About this part

The Bykski CC-UQD4D-X is a stainless-steel quick connect fitting with a built-in shutoff valve, made for server, data center and PC liquid cooling loops. It fits any G1/4 port, so it threads straight into standard blocks, radiators and other loop parts.

A quick connect lets you split the loop and remove a component without draining all of it, because the shutoff valve closes the line when it is separated. That makes maintenance, upgrades and moving hardware faster and cleaner. The stainless steel body suits a loop that will be connected and disconnected again and again.

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.

Questions people ask about this part

Answers specific to CC-UQD4D-X. If yours isn't here, ask — we'd rather talk you out of the wrong part than sell you one.

What does this part fit?
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-UQD4D-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?
PrimoChill, from Boise, Idaho. Every claim is handled directly by our support team 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.
