Pneumatic Lockout devices help prevent equipment from being energized by compressed air during servicing. They secure pneumatic fittings, couplers, and regulators so a hose cannot be reconnected to a pressurized air source until authorized removal of the padlock(s)—supporting safer, more consistent lockout/tagout execution.

Why lock out compressed air?

Pneumatic energy can cause unexpected movement, ejection, or tool activation. A dedicated pneumatic lockout helps prevent a quick-disconnect fitting from being reconnected to an air line while maintenance or adjustment is in progress.

Typical applications

- Air tools and pneumatic actuators

- Compressed air distribution and quick-connect points

- Packaging lines, assembly cells, and maintenance routes

- Facilities with frequent hose swaps or portable equipment

Stops accidental reconnection

Physically blocks coupling to the air supply until padlocks are removed.

Supports group lockout

Multi-hole designs can work with hasps to support multi-worker procedures.

Audit-friendly consistency

Clear lockout points help technicians follow procedures across shifts and areas.

Pneumatic lockout device types (selection overview)

Pneumatic lockouts are typically chosen by connection type (quick-disconnect vs. regulator/fitting), fitting size, and how many workers need control. Below are common options used in manufacturing facilities.

Pneumatic Quick-Disconnect Lockout

Applied to the male fitting to help prevent reconnection to compressed air sources during maintenance.

- Designed for common quick-disconnect systems

- Often supports common male fitting sizes (e.g., 1/4", 3/8", 1/2")

- High-visibility color options for compliance programs

Multi-Hole Pneumatic Lockout (Scissor Style)

Universal, inter-lockable designs that can support multiple padlocks for group lockout.

- Multiple lock points to control access

- Often used with hasps for multi-worker procedures

- Material options include stainless steel or engineering plastics based on environment

Large Electrical / Pneumatic Lockout

For broader isolation needs where a larger enclosure or multi-use lockout body is preferred.

- Useful for site-standardized procedures

- Often selected for durability and visibility

- Works well as part of a portable lockout kit

Not sure which type fits your coupler?

Send photos of your quick-disconnect and the fitting size. We’ll recommend the correct pneumatic lockout option and matching padlocks/tags.
