Key Features
- Compression fittings and unions provide a leak-resistant connection between two pipes
- NDS offers a wide range of sizes in compression couplings, adapters, tees, unions, and union adapters
- Compression fittings have an adjustable nut on each end to tighten and secure it in place
- Unions are used to connect pipes and provide a quick way to separate pipes when needed; no glue required
- Product is NSF/ANSI 61 + 372 listed
Applications
- Compression couplings connect two sections of pipe together to direct flow one-way through system
- Compression tees adds a “T” intersection from one pipeline splitting off into two different directions to create a lateral branch in system
- Compression adapters transition from unthreaded to threaded pipe to direct flow one-way through system
- Unions connect pipe without the need for traditional glued sealant; center of union can be pulled apart to quickly disconnect pipes
- Use for pool and spa, irrigation, and plumbing applications; works with most plastic pipe to transport water and provide a leak-resistant connection
Materials & Sustainability
- Compression fittings and unions are made of polyvinyl chloride (PVC)
- Union has an EPDM O-ring in center to create leak-resistant seal
- Onsite flow management helps provide a leak-resistant and corrosion-free system
Installation & Maintenance
- Compression fittings have slip or threaded ends that connect to pipe ends; use solvent to secure slip end
- Unions have two slip or threaded ends that connect to pipe ends; no glued sealant necessary
- Compression fitting performance issues can indicate damage; replace as needed
