PlymoVent hose fittings are connection tools between pipes and are detachable connection points between components and pipes. Main pipe fittings come in a wide variety of types. Commonly used pipe fittings can generally be divided into two categories: rigid pipe fittings and hose fittings. Rigid pipe fittings include flared, compression, and welded types, while hose fittings are primarily crimped rubber hose fittings. A compression pipe fitting consists of three parts: the fitting body, the ferrule, and the nut. When the ferrule and nut are placed on the steel pipe and inserted into the fitting body, tightening the nut causes the outer side of the ferrule's front end to fit against the conical surface of the fitting body, and the inner cutting edge uniformly bites into the seamless steel pipe, forming an effective seal. These are sealed pipe fittings suitable for non-corrosive or corrosive media such as oil, water, and gas. The specifications for use with aluminum-plastic pipes are relatively flexible. After connection to the pipeline, they feature reliable connections and good sealing performance.

PlymoVent hose fitting selection

Unidirectional flow type: Rotary joints are installed at both ends of the drum. Fluid enters from one end and exits from the other, without using an inner tube. Unidirectional flow type: A rotary joint is installed at one end of the drum, where fluid is both introduced and discharged. The inner tube remains stationary relative to the rotation of the drum. Bidirectional flow type (inner tube fixed): Unlike the previous type, this configuration includes different types of siphon tubes inside the drum to discharge condensate. This type is mostly used for steam applications. Bidirectional flow type (inner tube rotating): This type is used in structures where the inner tube is fixed relative to the drum and rotates synchronously with it. In this case, fluid is introduced through the inner tube and discharged through the outer tube. Bidirectional flow type (inner tube rotating): A siphon device that rotates synchronously with the drum is installed inside the drum to discharge condensate. This type is mostly used for steam applications.

PlymoVent hose fitting installation

Installation is the most critical step, directly affecting the reliability of the seal. Specialized pre-assembly tools are generally required. Fittings with small diameters can be pre-assembled on a bench vise. The specific procedure involves using a fitting body as the base, pressing the nut and ferrule onto the pipe. The main types include compression straight-through pipe fittings, compression end-straight pipe fittings, and compression tee pipe fittings. The depth of the conical hole in these fitting bodies often varies. As a result, if a pipe pre-assembled for a straight-through fitting is used for a tee fitting connection, the spherical contact formed between the ferrule and the inner conical surface of the fitting body may not be tight, leading to leakage. This issue is often overlooked. The correct approach is to pre-assemble the corresponding connection end with the same type of fitting as the one used to connect the other end of the pipe. This maximizes the avoidance of leakage problems. Try to maintain the coaxiality of the pipe and the fitting body; excessive deviation of the pipe will also cause seal failure. The pre-assembly force should not be too high. The inner cutting edge of the ferrule should just embed into the outer wall of the pipe, and the ferrule should not show obvious deformation. If the ferrule deforms severely during pre-assembly, it will lose its sealing function.

PlymoVent hose fitting applications

Pipe fittings are connection tools between pipes and serve as detachable connection points between components and pipes. They play an indispensable role in pipe assemblies and are one of the two main components of hydraulic piping. Pipe fittings are used for straight-line connections, such as for instruments, with connection types including socket weld or threaded connections. They are mainly used for small-diameter, low-pressure pipelines, particularly at locations requiring frequent assembly and disassembly, or for final adjustment of pipelines using threaded fittings. The structural form should preferably adopt a metal-to-metal contact seal; gasket-sealed structures are typically used in general pipelines transporting water, oil, air, etc., and are manufactured from malleable cast iron. Additionally, usage requirements and price are factors considered during selection. Pipe fittings come in many varieties; commonly used fittings can generally be classified into hard-pipe fittings and hose fittings. If classified by the connection method between the fitting and the pipe, hard-pipe fittings include flare-type, compression-type, and welded types, while hose fittings are primarily crimped hose fittings. In hydraulic systems, the connection methods between pipes and fittings also vary; the pipe insertion end uses connecting threads. Tapered threads rely on their conical shape for tightening and use materials such as polytetrafluoroethylene (PTFE) for sealing, mainly applied in medium- and low-pressure hydraulic systems. Fine-thread threads provide excellent sealing performance and are frequently used in high-pressure systems, but they require combination washers or O-rings for face sealing; copper washers are sometimes also used. This type is more suitable for pipes with thicker walls, and its main components include the fitting body, tailpiece, and nut. During use, the fitting body is inserted into the target, and the aforementioned washers are used to seal the face; the joint between the fitting body and the tailpiece is sealed with rubber, and spherical sealing is sometimes also employed. As pipe fittings are detachable connection elements, in addition to meeting requirements for normal connection stability, strong sealing, reasonable dimensions, low pressure loss, and good manufacturability, they must also meet the requirement for convenient assembly and disassembly. Therefore, do not underestimate these small pipe fittings, as their existence supports the entire hydraulic system.
