Actual operating pressure and temperature should be confirmed according to the selected material, gasket, conveyed medium, pipe size and applicable project standard.
The ring crimping caps are available in the following stainless steel grades:
| Stainless Steel Grade | Equivalent Designations |
| SS304 | 0Cr18Ni9 / S30408 / SUS304 / 1.4301 |
| SS304L | S30403 / 1.4306 |
| SS316 | 0Cr17Ni12Mo2 / SUS316 |
| SS316L | S31603 / 1.4404 |
SS304 is commonly selected for general water-supply and building-service applications. SS316 and SS316L may be considered for applications requiring additional corrosion resistance.
The final material should be selected according to the operating medium, temperature, pressure, installation environment and applicable technical standard.
The socket end uses a ring crimping connection. During installation, the pipe is inserted into the socket and compressed with the appropriate ring crimping tool.
When used with a compatible gasket, pipe and installation tool, the connection provides a secure and leak-resistant termination without conventional threading or on-site welding.

For steam systems, confirm the gasket material, pressure rating and operating-temperature requirements with Lianhe before ordering.
The mechanically formed stainless steel construction provides strength and dimensional stability for compatible piping applications.
SS304, SS304L, SS316 and SS316L material options are available for different operating environments and corrosion-resistance requirements.
Stainless steel provides durability and wear resistance, helping reduce replacement and maintenance requirements when the product is correctly selected and installed.
As an end cap, the product terminates the pipeline without introducing unnecessary internal components into the piping route.
The mechanical ring crimping connection can provide reliable joint performance in appropriately designed piping installations subject to vibration or movement.
Stainless steel is durable and recyclable, making it suitable for long-life piping installations.
The ring crimping connection reduces the need for conventional threading or on-site welding, helping simplify installation.
The compact connection is suitable for both exposed and concealed piping systems, subject to applicable construction and inspection requirements.
Fast installation, durable stainless steel construction and limited routine maintenance can help reduce the overall cost of the piping system.
The stainless steel body provides resistance to wear under suitable operating conditions.
The product can be used in compatible drinking-water systems when the selected material, gasket and complete piping system meet the relevant sanitary requirements.
When installed with the correct gasket, pipe and crimping tool, the cap provides a secure and leak-resistant pipe-end connection.
