PPE 515404005 4.0 INCH X 5.0 INCH L 6MM 5-PLY SILICONE COUPLER UNIVERSAL

Drag racing and sled pulling places huge stress on your trucks silicone hoses in a very short period of time. >PPEs hoses were designed to handle the rigors of increased pressure during racing and competition. They are equally proficient at daily driving and towing heavy loads.

Each PPE performance Silicone Hose is strengthened with 5 plies of polyester rein FORced fibers making them very tough. The Fluorocarbon lining offers better lubricity (slippery and resistant to chemicals) and the silicone rubber construction ensures that they can withstand constant boost pressures from -76 degrees all the way to plus 437 degrees Fahrenheit. In short, PPE performance Silicone Hoses will not blow out like a stock hose will.

>PPEs Silicone Hoses are resistant to fuel, oil and chemicals while also being UV and Ozone resistant. These hoses can handle the extreme exposure that heavy usages puts upon them. With multiple sizes and configurations, there is a PPE performance Silicone Hose FOR every design application.

The PPE 515404005 4.0 Inch x 5.0 Inch L 6MM 5-Ply Silicone Coupler Universal is engineered FOR high-performance vehicles that demand resilience and reliability under extreme conditions. Designed FOR drag racing and sled pulling, this coupler addresses the immense stress placed on silicone hoses during intense competition. However, it's just as capable FOR everyday driving and managing heavy towing tasks.

Constructed with five layers of polyester-rein FORced fibers, the PPE silicone hose boasts exceptional toughness, surpassing standard options. Its specialized Fluorocarbon lining not only enhances lubricity—making it slippery and resistant to a range of chemicals—but also grips tightly under the pressures of regular use. This versatility allows it to withstand a temperature range from a chilling -76 degrees to a scorching +437 degrees Fahrenheit, ensuring it won’t rupture like conventional hoses often do.

Further highlighting its robustness, the coupler is resistant to fuel, oil, and various chemical exposures while being UV and ozone resistant. This feature guarantees it can endure the harsh realities of heavy-duty applications, ensuring longevity and consistent performance. With a generous selection of sizes and configurations available, there's a perfect PPE hose tailored to nearly every design requirement.

Key specifications include a 4-inch inner diameter, 5-inch length, and a FORmidable working pressure of 70 psi, with a burst pressure of 207 psi, allowing it to handle high-boost scenarios with ease. It features a thick 6mm wall, and each hose is emblazoned with the PPE logo, setting a standard in the industry. FOR optimal fit, hose clamps should be 1/2 inch larger in diameter than the hose ID. Experience performance that stands the test of time with the PPE silicone coupler.
