1. Features of the card protrusion: easy installation, no deformation inside and outside the joint, it is a live connection and easy maintenance. Scope of application: Pipeline drinking water system. Water treatment equipment system. Surface installation is more suitable, the main consideration is to replace the sealing ring, and the use of hot water systems should be avoided as much as possible. The advantage of this connection is that it is easy to install and maintain. It is relatively simple and convenient to replace the sealing ring in the pipeline, as long as the nut is unscrewed, the nut can be replaced. The disadvantage is that the application is single, the aging of the sealing ring in the hot water system is more prominent, and the cost is higher. Hidden plumbing and hot water systems are generally not recommended.
2. Compression features: easy installation, outer pipe joint. The inner rubber ring is pressed into a hexagonal shape. Scope of application: The cold water system pipeline is directly connected to the drinking water system, and the surface installation pipeline is more suitable. The advantages are: simple and convenient connection, short working time and moderate cost. The disadvantage is that the application is single, the maintenance is very troublesome, and the replacement of the sealing ring in the pipeline is more troublesome. Since the card is connected when connected, it needs to be cut and replaced at both ends of the pipe to replace the hot water system.
