接头体

A compression fitting body that connects tubing to systems in industrial machinery.

技术定义与适配语境
典型 接头体 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

The fitting body is the main structural component of a compression fitting, designed to securely join tubing or pipes in fluid and pneumatic systems. It provides a leak-proof connection by compressing a ferrule against the tubing when tightened, creating a permanent mechanical seal without requiring welding or threading.

定义
The fitting body is the main structural component of a compression fitting, designed to securely join tubing or pipes in fluid and pneumatic systems. It provides a leak-proof connection by compressing a ferrule against the tubing when tightened, creating a permanent mechanical seal without requiring welding or threading.
工作原理
The fitting body works by housing a ferrule and nut assembly. When the nut is tightened onto the body, it forces the ferrule to compress radially onto the tubing, creating a tight seal between the tubing outer surface and the fitting body's internal taper. This compression creates both a mechanical grip and a fluid seal.
材料
Typically made from brassstainless steel (304/316)carbon steelor plastic (PTFEnylon). Material selection depends on application requirements including pressuretemperatureand fluid compatibility.
Tube Sizes
1/8" to 2" (3mm to 50mm)
Thread Types
NPT, BSPP, BSPT, SAE
Surface Finish
Ra 32 µin (0.8 µm) or better
Pressure Rating

常见问题

What is the difference between single ferrule and double ferrule compression fittings?

Single ferrule fittings use one ferrule that both seals and grips the tubing. Double ferrule fittings use two ferrules - the front ferrule creates the seal while the back ferrule provides the grip, offering better vibration resistance and reusability.

Can compression fitting bodies be reused?

The fitting body itself can typically be reused if undamaged, but ferrules should be replaced with each installation as they deform during compression to create the seal.
