外螺纹堵头就是通过螺纹或者螺纹的端面来实现封堵。常用螺纹有公制M螺纹，英制G  ZG,美制NPT等。材质可以根据用户需要。

外螺纹堵头

外螺纹堵头（Male Threaded Plug）是一种用于封闭管道、阀门或设备接口的密封件，通常具有外螺纹结构，可旋入内螺纹端口以实现封堵。广泛应用于液压、气动、石油、化工及工业管道系统。

外螺纹堵头核心特点

结构设计采用外螺纹（Male Thread）设计，与内螺纹（Female Thread）端口匹配，如NPT、BSPP、BSPT等标准螺纹。

材质多样，包括碳钢、不锈钢（304/316）、黄铜等，适应不同工况需求。

部分型号配备六角头或内六角结构，便于安装和拆卸。

外螺纹堵头功能优势

稳定密封：通过螺纹配合或附加密封垫（如O型圈、PTFE垫片）防止介质泄漏。

耐高压耐腐蚀：适用于高压系统（如液压管路）及腐蚀性环境（化工管道）。

可重复使用：螺纹结构允许多次拆装，维护便捷。

外螺纹堵头典型应用

液压管路的临时封堵或测试接口保护

阀门、泵体的备用端口密封

气动系统的管路末端防护

Male Threaded Plug Product Overview

The male threaded plug is a sealing component designed to close off pipe, valve, equipment ports, featuring external threads that screw into female-threaded openings. It is widely used in hydraulic, pneumatic, petroleum, chemical, industrial piping systems.

Key Features

Structure Design

Male threads (e.g., NPT, BSPP, BSPT) compatible with female-threaded ports.

Materials include carbon steel, stainless steel (304/316), brass, etc., for diverse working conditions.

Some models feature hex heads internal hex sockets for easy installation/removal.

Functional Advantages

Leak-proof Sealing: Achieved via threaded engagement auxiliary seals (e.g., O-rings, PTFE gaskets).

High Pressure & Corrosion Resistance: Suitable for hydraulic systems corrosive environments.

Reusable: Threaded design allows repeated disassembly for maintenance.

Typical Applications

Temporary sealing test port protection in hydraulic pipelines

Backup port sealing for valves pumps

End-of-line protection in pneumatic systems

注：术语可能因标准而异，如 "Pipe Plug" 或 "Threaded End Cap"，螺纹类型需明确标注（如NPT、BSP）。
