This type of sealant cord provides a robust alternative to traditional PVC tubing when flexibility and adaptability are paramount.
FAQ
What pressures can Sealant Cord handle?
Sealant Cord is generally rated up to 6 bar (90 psi) at room temperature, however, this can decrease with higher temperatures. Always consult the manufacturer's specifications for precise pressure limits before use.
How do I join lengths of Sealant Cord together?
You’ll typically need a hose clamp or compression fitting to securely connect sections of sealant cord. Ensure the surfaces are clean and dry before applying the clamp for a watertight connection.
Is Sealant Cord suitable for hot water systems?
While Sealant Cord can handle moderately warm water, it’s not recommended for consistently high-temperature applications or direct exposure to boiling water. Check the manufacturer's data sheet for temperature ratings.
What tools do I need to work with Sealant Cord?
You’ll require a utility knife or sharp scissors for cutting the cord accurately, as well as pliers for gripping and manipulating it during installation. A measuring tape is also useful for determining required lengths.
How does Sealant Cord compare to PVC tubing?
Sealant Cord offers significantly greater flexibility than rigid PVC tubing, making it easier to navigate around bends and fittings in tight spaces. However, PVC may be more suitable where extreme pressure resistance is needed.
What’s the typical lifespan of Sealant Cord?
With proper installation and use, Sealant Cord can last for several years, although this depends on water quality and operating conditions. Regular inspection for cracks or deterioration is advisable.
Can I use Sealant Cord outdoors?
Sealant Cord *can* be used outdoors, but prolonged exposure to UV radiation will degrade the material over time. Consider protecting it with a sleeve or running it through an internal pipe if possible.
What’s the best way to clean Sealant Cord?
Avoid using harsh chemicals or abrasive cleaners as these can damage the tubing's surface. A mild detergent and warm water solution is generally suitable for cleaning, followed by thorough rinsing.
Does Sealant Cord require any special fittings?
Sealant Cord typically uses standard compression fittings designed for flexible tubing, ensuring a secure and leak-proof connection with other plumbing components.
What’s the minimum internal diameter of Sealant Cord?
The standard internal diameter is 13mm, but always verify this against your specific fitting requirements to ensure compatibility before commencing work.
