Plasson Polypropylene Threaded Fittings

Plasson Polypropylene Threaded Fittings are a high-quality, durable solution for creating BSP threaded connections within cold water systems. Manufactured by Plasson—a global leader in water distribution components—these fittings are engineered from tough, chemical-resistant polypropylene and designed for long-term performance. Available in both male and female BSP threads, this comprehensive range includes couplers, adaptors, elbows, tees, and hose connectors. Suitable for both domestic and commercial use, these fittings offer superior reliability compared to low-cost alternatives.

• Cold Water Distribution Systems: Ideal for non-pressurised or low-pressure pipework requiring secure threaded joints.
• Agricultural and Irrigation Installations: Widely used in systems involving hose connections, taps, and tank fittings.
• Industrial and Workshop Environments: Suitable for non-aggressive fluid handling and service lines.
• Utility and Temporary Installations: Provides quick and versatile connection options for portable and semi-permanent water systems.

• Material: High-grade black polypropylene
• Thread Types: Male BSP, Female BSP
• Product Range Includes:
• Threaded couplers
• Hose adaptors
• Tees, elbows, and nipples
• Reducing fittings and end caps
• Thread Sizes: Typically 3/8" to 2" BSP (varies by fitting)
• Temperature Range: Suitable for cold water use only (0°C to approx. 40°C)
• Chemical Resistance: Excellent resistance to most non-aggressive chemicals and agricultural fluids
• Pressure Rating: Varies by fitting and thread size (consult individual datasheets)
• Standards Compliance: Manufactured following relevant BSP and ISO standards

• Thread Preparation

Clean both male and female threads before installation.
Apply PTFE tape to male threads (avoid sealing paste, which may degrade the plastic).

• Assembly

Hand-tighten the fitting onto the male thread.
If required, use a strap wrench to gently tighten—do not overtighten as this can damage the threads.

• Hose Connection (if applicable)

Fit the hose over the barbed adaptor and secure with a jubilee clip or suitable hose clamp.

• Testing and Use

Once assembled, pressure test the system at its intended operating pressure.
Check for leaks and inspect for proper alignment before final commissioning.
