4,000 types of caps and plugs
- A large number of standard stock items - Save on your mold costs by utilizing our existing molds - Protective and masking (heat-resistant silicone up to 220°C) - Caps and covers that fit over the outside - Plugs and stoppers that fit inside - Other painting dots, tapes, and grips, etc.
Caps and plugs ideal for shipping protection.
The P series with pull-out tabs, the Y series with tear tabs, and pipe inserts are all standard products, but we offer a wide variety of shapes and sizes. Their lightweight nature is the biggest feature, making them particularly advantageous for large products and contributing to reduced transportation costs. ● In addition to the conventional tapered plugs, we have significantly expanded our product lineup. While polyethylene products lack elasticity, we have prepared various shapes to ensure adequate compatibility.
Silicone Pull Plug SPP Series
The pull tab designed with a diameter smaller than the masking diameter makes attachment and detachment easier. While the main plug designed with a diameter larger than the masking diameter is compressed, sufficient sealing can be achieved.
Washer Plug WP Series
Since it has two types of plugs in one, it can reduce material and transportation costs.
Screw-type plug FP series
It is compatible with UNF and UNJ screws for aviation, aerospace, and other equipment. The outer part of the plug is also threaded, allowing for a tight seal. The knob on the top of the plug is designed for easy gripping. ● Size types: 11 types from 5/16-24 SAE to 1-5/16-12 SAE ● Color is red, material is LDPE.
Masking Pro
We simplify the labor-intensive masking process, not only increasing the productivity of painting but also offering materials such as silicone (for high temperatures) and EPDM (for chemical resistance) that cater to various applications. Additionally, we provide tapes and discs that are widely used in many fields. ● In addition to conventional products, we offer washer plugs that can seal three different diameters with one piece. We also have a wide range of special shapes, including pull plugs that are ideal for parallel threads.
Cover Plug YP Series
Originally designed for connector covers of consumer electronics, it is widely used for general purposes due to the ease of pulling out the flange part (the lip on the back of the opening).
Corn cap plug
Compatible sizes φ3.8 to φ14.8 The shape is a simple cone. One plug accommodates a wide range of sizes. Color-coded for each hollow processing size to flexibly adapt to hole sizes.
Cap and plug for mold cost savings.
Typically, caps, covers, plugs, and stoppers that are usually produced using molds are introduced as standard products at Sinclair & Rush. For example, threaded caps and terminal caps for UNF11/16.
Plug-in Plug I Series
It is designed to be inserted with one push into screw holes of specific sizes. It is easier than screw plugs but provides sufficient sealing. It is based on inch screws, but we also have options that can be applied to M screw sizes. ● Size types: 13 types from M6, 1/4 inch to M27, 1-1/16 ● Color is yellow, material is LDPE.
It's easy to enter because it's hollow! Effective for cost reduction!
The hollow part provides elasticity and fits diameters that conventional plugs 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.
Pull Ring Plug PR Series (Plug for NPT)
This type has a ring on the outer circumference of the standard tapered plug cap, making it significantly easier to remove the plug. It is available based on NPT sizes. - Size range: from NPT 1/8 to NPT 2” - Some items are available for immediate delivery from stock in Japan - Color: blue - Material: LDPE

PT screw J-SR plug series
- The sizes range from PT1/8 to PT1 inch. - The material is flexible and stretchable PVC, which is expected to improve work efficiency compared to harder materials like polyethylene. It can be used outdoors without cracking, allowing for long-term use. - The 360-degree pull tab enhances ease of attachment and detachment.
