Overview

The ADD W1 internal hose support spring is a stainless steel coil designed to reinforce vacuum hoses and prevent them from collapsing under high-vacuum conditions. It fits inside the hose to provide structural support while maintaining airflow, making it ideal for PCV, CCV, and oil catch can applications. The spring is 36 inches long and can be trimmed to the required length or used with multiple springs for longer installations. It is available in 15mm hose / AN10 and 19mm hose / AN12 sizes.
Show original supplier description
The ADD W1 internal hose support spring is constructed from durable stainless steel, designed to provide critical reinforcement to vacuum hoses. This coiled spring is inserted directly into the hose, preventing it from collapsing under high-vacuum conditions common in demanding PCV, CCV, and oil catch can systems. By maintaining the hose's structural integrity, it ensures consistent airflow, which is particularly beneficial in heavily modified or high-performance applications. Each spring measures 36 inches in length and can be easily trimmed to fit specific hose requirements. For longer hose runs or enhanced support, multiple springs can be placed end-to-end within the same hose to create continuous reinforcement. This product is available in two sizes to accommodate different hose diameters: 15mm hose / AN10 and 19mm hose / AN12. Key features include its durable stainless steel construction, its ability to prevent vacuum hose collapse, and its role in providing internal hose reinforcement. The design ensures that airflow is maintained even under significant vacuum. This makes it a suitable accessory for various PCV, CCV, and oil catch can setups.
