Shopping and Ordering

  • Can I have a coupon applied retroactively?

    As a general rule of thumb, no. We always advise being careful at checkout to ensure that everything is entered correctly and as you want. While it would be nice for it to be as simple as issuing a partial refund, there’s more to it than that.
  • Can I pre-order an item?

    Usually no, but pre-ordering is occasionally enabled for new product releases.
  • Do I need to make an account prior to ordering?

    An account is currently not required for ordering, but an email address is. Some of your information will be saved for billing and accounting purposes, however. Having an account with us is optional.
  • How big of a radiator do I need?

    This answer varies based on the heat load of your loop and your specific goals with the loop. It will also vary based on the performance of the fans you intend to use and the airflow restriction (if any) of your case. A good starting place these days is a 240mm radiator per component. 120mm per w...
  • Is (cleaner) toxic?

    No. None of them are toxic, although Rad Clean is a relatively strong acid. Care should still be taken not to ingest them.
  • Is this item in stock?

    Any items that show in stock, we have. We do not sell items we don’t have except in the case of rare pre-orders or errors in inventory that we work hard at maintaining accurately. If you've ordered the last of an item we also sell on third party sites under seller name Tyler Direct, we may not be...
  • What do I need for a full loop?

    You’ll need at least one block, fittings, tubing, radiator(s), coolant, cleaners, and a pump with some kind of pump top. While technically optional, a reservoir is highly recommended and can serve as the pump top with the right model. Distro plates can replace a traditional tube reservoir, as wel...
  • What hard tubing size should I use?

    This is mostly going to be up to your personal preferences and goals with the build. 12mm and ½” tubing are small, don’t distract as much from other elements of the build, and are somewhat easier to bend. The fittings for them can also be more compact in size. 16mm has been gaining popularity for...
  • What metals are safe?

    In this industry, the primary metals used in contact with coolant are Copper, Nickel, Stainless Steel, and Brass. These metals are considered safe together, having low galvanic potential between each other. Our coolants help mitigate these minor differences in potential. Aluminum and Zinc are two...
  • What soft tubing size should I use?

    This will depend on your particular use case. 3/8x1/2” is technically more flow-restrictive than some of the larger ID options like 7/16” or 1/2“ ID tubing, but takes less room and draws less attention than the larger sizes. Thicker walled tubing like 3/8x5/8” is less prone to kinking around tigh...
  • What tools do I need to build a soft tubing loop?

    Generally very few, primarily just a tube cutter. Many blocks may require a phillips head screwdriver, others may require allen keys. Some can be assembled entirely by hand, using thumb screws instead of tools.
