Per the VRC Game Manual, there are three types of pneumatic components permitted in the VEX Robotics Competition:
- The official V5 Pneumatics Kit (released in 2023), manufactured by and purchased from VEX
- Legacy (pre-2023) components purchased directly from VEX
- SMC components that are equivalent to the legacy VEX components, but manufactured by and purchased from SMC (or an SMC reseller)
This article is intended to be a visual inspection reference that will help clear up any confusion regarding differences in part numbers or appearance. The parts below are the ONLY pneumatic components that are VRC legal; parts which look similar to a legal part in all ways except color or material are prohibited.
Note: This article replaces the “Legal Pneumatic Parts” PDF document that was used previously (prior to the 2023 season), and is considered an official reference for competition legality.
V5 Pneumatics Kit
- There are no SMC equivalents for parts found in the V5 Pneumatics Kit.
- The V5 Pneumatics Kit and legacy/SMC parts are compatible; using parts of both types on the same robot is legal, provided no other rules are violated.
- See this article from the VEX Library for more information about each component, including a diagram of one possible configuration.

Note: The V5 Pneumatics Kit includes a valve stem with either hexagonal or knurled cylindrical bosses. Note that both versions are officially permitted for use in the VEX Robotics Competition.
