Marley High Pressure Solvent Cement (MP250, MP250B, MP500)

We trust Marley High Pressure Solvent Cement in our plumbing projects, relying on MP250 for general applications, MP250B when we need visual confirmation with its blue tint, and MP500 for tougher PVC and UPVC jobs under higher pressure. These cements give us strong, leak-proof joints and are easy to apply for both residential and industrial needs. For best results, we always follow safe handling and storage tips to guarantee performance and safety. Construction Hyper

Key Takeaways

• MP250: Designed for standard PVC pressure pipes in general plumbing and irrigation.
• MP250B: Blue-tinted variant for visible application verification, ideal for compliance-driven projects.
• MP500: Suitable for PVC and UPVC, engineered for higher pressures and demanding industrial conditions.
• All Marley solvent cements provide strong, leak-proof bonding with fast set times.
• Proper application requires cleaning, roughening, even coating, and twisting pipe into fitting.
• Safety essentials: gloves, eye protection, ventilation, and sealed storage away from heat and sunlight.

Understanding the Differences: MP250 vs MP250B vs MP500

Choosing the right Marley solvent cement depends on project requirements:

• MP250 is the reliable choice for standard PVC pressure pipes and fittings.
• MP250B offers a blue tint, making it easy to visually confirm application coverage.
• MP500 is formulated for both PVC and UPVC, handling higher pressures and harsher industrial conditions.

By matching the cement to the system, we ensure lasting, pressure-tight joints.

Key Features and Benefits

• High-strength bonding for watertight joints.
• Smooth consistency for easy, uniform application.
• Fast set times for quicker pressure testing.
• Chemical and pressure resistance for diverse plumbing and industrial environments.

Step-by-Step Guide to Proper Application

1. Prepare surfaces: Clean pipe ends and fittings thoroughly, removing dirt, grease, and moisture.
2. Roughen surfaces: Lightly sand for better adhesion.
3. Apply cement: Use the supplied brush to coat both pipe and fitting evenly.
4. Join quickly: Push pipe into fitting with a slight twist to spread cement.
5. Hold firmly: Maintain pressure for a few seconds to secure the bond.
6. Cure properly: Allow recommended curing time before pressure testing.

Common Use Cases

• Residential: Water supply lines, waste systems, irrigation setups.
• Commercial: Water distribution, HVAC piping, drainage systems.
• Industrial: High-pressure pipelines, chemical processing, aggressive fluid transport.

Tips for Safe Handling and Optimal Performance

• Wear gloves and safety glasses.
• Work in well-ventilated areas.
• Store sealed in original containers, away from sunlight and heat.
• Check consistency and expiration date before use.
• Always clean and dry pipe surfaces before application.
