Reinforcing sockets for PA12 tubes are essential metal inserts that strengthen the ends of DIN 73378 PA12 tubes. They prevent tube deformation when used with DIN 3871 socket unions and compression fittings, ensuring a secure, leak-free connection in centralized lubrication and pneumatic systems. This guarantees long-term reliability and system safety.

Reinforcing Sockets for PA12 Tubes: Essential Supports for Secure Connections

Overview


Reinforcing sockets for PA12 tubes (also known as tube support inserts or stiffening sleeves) are critical precision components engineered to ensure the long-term integrity and reliability of connections in centralized lubrication systems and pneumatic circuits. Designed to be inserted into the ends of semi-rigid DIN 73378 PA12 (Polyamide 12) tubes, these metal sleeves internally reinforce the tube wall. This prevention of tube collapse and deformation under compression is vital for creating a perfect, leak-free seal when used with standard compression fittings, particularly DIN 3871 socket union fittings and DIN 3862 double cone olives.


Key Features & Benefits

Prevents Tube Deformation & Blow-outs: The primary function of the reinforcing socket is to provide internal support to the PA12 tube end. This prevents the tube from collapsing or flaring when the compression nut is tightened, ensuring the tapered sleeve (olive) can seal effectively against a rigid structure.


Ensures Reliable, Leak-Proof Seals: By maintaining the tube's circular shape and dimensional stability under pressure and vibration, the insert guarantees a consistent and durable metal-to-metal seal with the fitting, eliminating the primary cause of connection failure in lubrication systems.


Enables Higher System Pressure: Allows the PA tubing to be used safely at the full rated pressure of the compression fitting by reinforcing its weakest point—the connection end.


Standardized for Perfect Compatibility: Manufactured to precise dimensions that correspond with standard DIN 73378 tube outer diameters and the internal geometry of DIN 3871 socket unions, ensuring a perfect fit and optimal performance.


Simplifies Assembly & Improves Safety: Makes the installation of screwed connections and push-in fittings more straightforward and reliable, significantly reducing the risk of installation errors and subsequent fluid leaks or system failures.

Typical Applications

Centralized Lubrication Systems: An essential component for securing PA12 lubrication lines to pumps, meters, injectors, and manifolds using DIN 3871 socket unions and double cone olives. Critical for single-line, dual-line, and progressive systems.


Pneumatic Systems: Used to reinforce tube ends in compressed air lines where push-in or compression fittings are employed, preventing leaks and maintaining system efficiency.


General Industrial Fluid Power: Provides reliable tube support in any application using semi-rigid plastic tubing (PA, PU) with compression-style fittings for fluids like coolants or low-pressure hydraulics.


How It Works: The Critical Link in the Connection

A secure connection with a PA12 tube requires a reinforced structure. The reinforcing socket is inserted into the tube end. When the assembly (tube + insert) is placed into a DIN 3871 socket union and the compression nut is tightened onto a DIN 3862 olive, the metal insert absorbs the compressive forces. It prevents the soft nylon tube from deforming inward or outward, allowing the olive to bite and seal uniformly against a solid foundation. This process transforms a vulnerable plastic tube end into a robust, pressure-ready connection point.


Never compromise on connection integrity. Ensure every PA12 tube fitting in your lubrication system is supported with the correct reinforcing socket. Contact us for sizing assistance and technical data.
