PrimoChill RSX Replacement Cap Switch Over Kit 1/2in - Silver Nickel

Our review of the PrimoChill RSX Replacement Cap Switch Over Kit finds it best for PC builders who want to change the color of existing Revolver or Rigid Ghost fittings without replacing whole fittings. The kit includes 12 Revolver SX caps, a bottom sealing o-ring, a tubing sealing o-ring and a removal tool, and it supports the common 3/8 in ID x 1/2 in OD rigid tubing types. For anyone reworking a custom water cooling loop, the biggest reason to buy is simple: quick color swaps that preserve the original fitting bases and save the cost and effort of buying all-new fittings.

Key Features

• Color flexibility: Offers a choice from multiple colors so builders can match or refresh a loop without replacing fitting bases.
• Compatibility: Works with original Rigid Ghost fittings and current Revolver fitting bases to avoid mixing component generations.
• Includes sealing parts: Comes with both a bottom sealing o-ring and a tubing sealing o-ring to maintain leak-free connections after cap replacement.
• Tool and removal aid: A Revolver removal tool is included to ease cap removal when needed, reducing the risk of damage during servicing.
• Rigid tubing support: Designed specifically for 3/8 in ID x 1/2 in OD rigid PETG, PMMA, and copper tubing for predictable fit and seal.

Who It's For

This kit is ideal for PC enthusiasts and modders who already own Revolver or Rigid Ghost fitting bases and want to change the visual theme without re-buying entire fittings. It suits builders doing refreshes, color swaps, or phased upgrades where cost and parts reuse matter.

It is not for someone who needs full new fittings or a different tubing size; if you are switching to flexible tubing or a different diameter, look for complete fittings made for that tubing. Also, this kit only provides caps and a small set of o-rings, so new builders without fitting bases should consider full fitting kits instead.

Pros & Cons

Pros

• Enables quick aesthetic swaps while keeping existing fitting bases, saving money.
• Includes both sealing o-rings to help ensure reliable, leak-free connections.
• Compatible with the common rigid tubing materials used in many custom loops.
• Removal tool included to simplify maintenance and reduce risk of damaging fittings.

Cons

• Caps alone cannot convert flexible tubing systems or other tubing diameters; buyers must already have compatible bases and 3/8 in ID x 1/2 in OD rigid tubing.
• Color selection requires choosing the correct cap color up front since only caps are provided in the 12-pack.
