Tongue-type (pull-tab) plug P series
We designed a pull tab for the standard tapered plug cap. Removing the plug has become significantly easier. While it is based on NPT sizes, we also have options that can be applied to PT sizes. ● Size varieties: From PT 1/8 to PT 2”, a total of 12 types ● Some are available for immediate delivery from stock in Japan. ● Color is blue, and the material is LDPE.
Plug-in Plug SR1011 Series
It is designed to be inserted with one push into screw holes of a specific size. Although it has a slightly thicker shape rather than a taper, it offers better sealing than tapered plugs. It is based on metric screws. There is a wide range of hole diameters available. ● There are 25 types of sizes, with hole diameters ranging from 6.6 to 33.0. ● Most are available for immediate delivery from stock in Japan. ● The color is milky white, and the material is LDPE.
Flangeless Plug FLPS Series
Compatible sizes φ3.0 to φ30 For threaded holes (not suitable for unthreaded holes.) Easily fits taps with a textured surface Includes a knob for easy removal Color-coded by size
EPDM plug
It has excellent chemical resistance. Although it is inferior to silicone, it can also withstand high temperatures and can be reused for masking and finishing. ● Ideal for painting and coating. ● The V-shaped design allows one plug to fit several types of ports. ● Sizes that are usually hard to obtain are also available.
Because it's a hollow type, it's easy to enter! Effective for cost reduction!
The hollow part has elasticity and fits diameters that conventional ones of the same size could not accommodate. Additionally, since the material does not cover the hollow section, the price is lower than that of conventional plugs.
Handle-equipped plug
This is a plug with a handle attached to a tapered silicone shape. It is a product with good workability for attachment and detachment. The shape is specially designed for powder coating and "E" coating finishing systems, allowing it to be safely used at extremely high temperatures of up to 232°C. ● It is reusable. The number of uses varies depending on the temperature of use. ● It is color-coded by size, making it easy to distinguish. ● It does not harden or crack.

This is a mechanical plug for closing off heat exchange tubes. It is a revolutionary maintenance method that eliminates the need for welding closures in high-pressure equipment.
In the maintenance of heat exchanger tubes, I believe that the current methods involve driving in taper pins to seal leaking tubes or using seal welding for high-pressure equipment. The Pop-A-Plug from Curtis Wright in the United States uses a specially machined mechanical structure plug that is sealed with a dedicated tool. It maintains pressure resistance up to about 40 MPa, and seal welding after plugging is not required (the maximum pressure resistance varies by size). Welding work requires time for the work itself, pre-treatments such as heat treatment, applications related to the use of fire, and inspections during the welding process. However, Pop-A-Plug can reduce this workload and does not use heat, so there is no damage to the equipment. It is a sealing method that can significantly shorten the recovery period of the equipment. *According to ASME PCC-2-2022, the guidelines for the maintenance of pressure equipment, Pop-A-Plug is recommended as a tube plug for heat exchangers. *For more details, please download the PDF or contact us.
![Plug for pressure testing of pipe flanges [for high pressure/neck flanges]](https://image.www.ipros.com/public/product/image/676/2000581796/IPROS29419732567328402021.gif?w=280&h=280)
This is a plug that allows for isolation and pressure testing after welding to be conducted locally during the replacement work of the weld neck flange. [Maximum pressure rating: 15.5 MPa]
During flange replacement work at plant piping maintenance sites, localized welding points can withstand pressure tests up to 15.5 MPa. - Localized response with a plug eliminates the need for ancillary work. - Significant reduction in labor (cost) is achieved. - Can be reused multiple times. - Localized testing allows for a reduction in the amount of medium used. This is a plug compatible with weld neck flanges. There are also high-lift flange welding test plugs compatible with slip-on flanges and others. *For more details, please download the PDF or contact us.
