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.

About this part

This Bykski Push Lok Plus Flexible Durable Server Tubing 10mm (3/8in) ID Single Fiber Braid – 10 Feet (B-PK-801-6-BLK) is engineered for secure, tool-free push-lock connections in demanding server and custom liquid-cooling loops. The single fiber braid reinforcement resists kinking and collapse under bend, while maintaining flexibility for tight-routing in dense builds. Its 10mm inner diameter supports steady flow, helping keep components cooler and systems reliable.

A smooth-bore design supports consistent coolant flow and minimizes turbulence. The tubing is optimized for use with Bykski Push Lok Plus fittings and similar push-lock barbs sized for 10mm ID tubing. Suitable for series or parallel loop routing, with dependable grip strength to reduce the risk of slip-offs when properly installed.

Questions people ask about this part

Answers specific to B-PK-801-6-BLK-10. 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

  • Push-lock style fittings sized for 10mm (3/8in) ID tubing (Bykski P-Lok Fitting)

Check those against your build before you order. If anything does not match, ask us first — it is cheaper than a return. Part number B-PK-801-6-BLK-10.

Is it in stock, and when will it ship?
Yes — only 8 left in Boise, Idaho. Orders placed before 2:00 PM MST on a business day ship the same day — we do not ship weekends or US holidays. Overnight delivery is available at checkout.
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 and we'll confirm the right part before you spend $66.99 — 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.
