ERA Sch 80 CPVC 2 Inch Compact Ball Valve, Socket
- Brand: ERA
- CPVC construction for chemical and corrosion resistance
- High strength with better heat and pressure resistance than PVC
- Connection: Socket; sizing: Schedule 80
Best for: Systems needing reliable flow control in higher-temperature, higher-pressure water or chemical lines. Choose this when a compact valve must fit tight spaces without sacrificing performance. Limitation: Socket joints require primer and cement for installation.
ERA Sch 80 CPVC 2 Inch Union, Socket
- Brand: ERA
- CPVC for chemical and corrosion resistance
- High strength; improved resistance to high temperatures and pressures
- Connection: Socket; sizing: Schedule 80
Best for: Maintenance-friendly runs where sections must be easily disconnected for repairs. Better if you need to service a portion of the line without draining the entire system. Caution: Ensure proper alignment during installation to avoid leakage at socket joints.
(5 Pack) ERA Sch 80 CPVC 3/4 Inch Union, Socket
- Brand: ERA
- CPVC for chemical and corrosion resistance
- High strength; better resistance to high temperatures and pressures than PVC
- Connection: Socket; sizing: Schedule 80
Best for: Branch lines on a moderate scale where multiple unions help with future maintenance. Choose this for flexible layouts in smaller projects. Limitation: Five-pack units may be more than needed for very small jobs.
ERA Schedule 80 CPVC 2 Inch Male Adapter, Socket x Male NPT
- Type: Schedule 80 CPVC Male Adapter
- Connection: Socket X MNPT
- Operating Temperature: 32-200°F
Best for: Converting socket ends to male NPT threads for threaded connections within CPVC systems. Better for projects requiring threaded joins in a CPVC network. Caution: Check thread compatibility and use CPVC primer and cement for joints.
ERA Sch 80 CPVC 1-1/2 Inch True Union Ball Valve, Socket Connection
- Brand: ERA
- True Union design enables easy removal of the valve body
- CPVC construction for chemical and corrosion resistance
- Operating temperature: 32°F to 200°F
Best for: Industrial and plumbing systems needing straightforward maintenance and quick valve service. Better for future-proofing maintenance plans; avoid if space is extremely limited where extra hardware might be problematic.
ERA Sch 80 CPVC 3 Inch Union, Socket
- Brand: ERA
- CPVC for chemical and corrosion resistance
- High strength; resistance to high temperatures and pressures
- Connection: Socket; sizing: Schedule 80
Best for: Larger diameter branch connections where ease of disassembly and reassembly is valuable. Choose this when your system requires frequent access to downstream sections. Limitation: Larger fittings may require more space during installation.
Buying Guide: Key Considerations For Sch 80 CPVC Fittings
- Material compatibility: CPVC offers chemical and corrosion resistance, suitable for aggressive fluids. Confirm fluid compatibility with your specific chemical or water application.
- Schedule 80 advantages: Thicker walls provide higher pressure and temperature tolerance than Schedule 40. Ideal for demanding plumbing and industrial networks.
- Connection type: Socket connections require primer and cement; threaded (MNPT) adapters require proper threading and sealants. Choose socket or union designs based on maintenance needs and space constraints.
- Valve and fitting type: Ball valves provide precise flow control and quick shutoff. Unions enable easy disassembly for maintenance. Assess whether you need flow control, easy servicing, or a combination.
- Size and layout: Match pipe size to fittings to avoid performance losses. Plan for future expansion when selecting multi-pack options like unions.
- Installation considerations: Use CPVC primer and cement as required for socket joints; ensure clean, dry surfaces and proper alignment to prevent leaks.
- Temperature and pressure range: Check the operating range (often 32°F to 200°F for CPVC products) to ensure compatibility with your system’s conditions.
FAQ
- What is Sch 80 CPVC best used for? – It’s ideal for higher-pressure and higher-temperature applications with chemical resistance, such as industrial and chemical plant piping.
- Do CPVC fittings require special cement? – Yes, socket CPVC joints typically use a CPVC primer and cement to form a strong bond.
- Are unions better than regular fittings for maintenance? – Unions allow easier disassembly and maintenance without dismantling entire runs.
- Can I mix CPVC with PVC? – CPVC and PVC have different chemical compositions; it’s best to use CPVC fittings with CPVC piping to maintain performance and avoid leaks.
- How do I choose valve size? – Match valve size to the pipe size to ensure proper flow and pressure characteristics for your system.
- Is True Union worth it for all systems? – True Union valves are especially helpful in systems requiring regular maintenance or replacements without full system shutdown.
