Frequently Asked Questions
What is a dresser type ring seal used for?
A dresser type ring seal is used in dresser couplings and mechanical pipe joints to create a leak-proof connection between pipe sections. It accommodates slight misalignment, vibration, and thermal expansion, making it ideal for marine piping systems.
Is this ring seal compatible with seawater?
Yes, this ring seal is manufactured from marine-grade elastomers such as NBR or EPDM, which provide excellent resistance to seawater, oils, fuels, and chemicals commonly found in shipboard applications.
What pipe sizes does this seal fit?
The dresser type ring seal is available in sizes from 1/2" to 24" nominal bore to fit a wide range of marine piping systems. Custom sizes can be sourced upon request.
How do I install the ring seal in a dresser coupling?
To install, place the ring seal in the coupling sleeve, align the pipe ends, and tighten the bolts evenly to compress the seal and form a watertight joint. Ensure all surfaces are clean and free of damage before installation.
