SMC Plug Series Plug Fitting, 1/2 inch Connection Size, R 1/2 Thread Standard - PLUG1/2


This plug fitting provides a sealed closure for fluid or gas lines in industrial environments, designed to be installed into R thread connections to block flow when required. It operates under moderate thermal conditions and is intended for systems where a compact, serviceable end cap is needed.

Features and Benefits:


• R1/2 threaded connection offers secure engagement and leak prevention
• 1MPa maximum pressure rating supports medium-pressure systems
• 0-60°C operating temperature range suits temperate installations
• Hex socket head enables recessed tightening with Allen tools
• 1/2 in connection size fits common half-inch piping systems

Applications


• Suitable for isolating test ports on pneumatic manifolds
• Ideal for temporarily capping process sampling lines
• Used with hydraulic circuits within 1MPa pressure limits
• Can be used for closing unused branch connections in pipework
• Used for maintenance sealing where confined access exists

What tooling is required to install and remove this component?


Installation and removal use an internal hex key engaging the hex socket head to apply torque without obstructing adjacent fittings.

How should it be selected for temperature-sensitive installations?


Choose this item when system fluids remain within the 0-60°C operating window to avoid thermal overstress.

Is the connection compatible with standard tapered threads?


The part uses an R thread form and connects to mating R1/2 ports designed for that thread standard.

What pressure conditions must be observed during service?


Do not exceed the maximum operating pressure of 1MPa to maintain sealing integrity and prevent failure.
