Looking for a reliable, fast way to extend your irrigation zones or build a professional valve manifold? The Tavlit Nut Lock Swivel Tee 25mm – 1″ (NLT251S) is a premium irrigation fitting combining the absolute security of a Nut Lock compression mechanism with the convenience of a Swivel union.

Engineered for professional irrigation systems, commercial growers, and heavy-duty drip lines, this fitting ensures a completely leak-free setup capable of handling high water pressure with total peace of mind.

Key Features & Benefits:

• Secure Nut Lock Mechanism: The specialized internal split ring and outer locking nut grip the 25mm pipe directly onto the internal barb. This completely eliminates the risk of pipe blow-outs caused by water hammer.
• 1″ Female BSP Swivel Union: The free-spinning female threaded connection allows you to screw directly onto solenoid valves, filters, or manifolds without having to rotate the entire tee fitting. It is a massive time-saver in tight valve boxes.
• No PTFE Tape Required: The Swivel union features a factory-fitted captive EPDM rubber O-ring. This creates a 100% watertight seal with simple hand-tightening, completely removing the need for thread sealants.
• Tool-Free Installation: Ergonomically designed locking nuts allow for maximum leverage using just your hands, making on-site assembly, modifications, and winterisation quick and painless.
• Engineering-Grade Materials: Manufactured from UV-stabilised polypropylene (PP), this fitting is built to withstand harsh UK weather, ground movement, and agricultural chemicals.

Technical Specifications:

• Product Code: NLT251S
• Pipe Connections: 2 x 25mm (Nut Lock for PE / MDPE / LDPE pipe)
• Threaded Connection: 1 x 1″ Female BSP (Swivel Union Nut)
• Maximum Working Pressure: Up to 10 bar (PN10)
• Body Material: High-grade Polypropylene (PP)
• Seal Material: EPDM O-ring
• Compatibility: Standard 25mm OD irrigation pipes and thick-walled drip lines

Application:

The Tavlit NLT251S tee is a staple component for assembling valve manifolds inside underground valve boxes or splitting a 1″ threaded supply line into 25mm lateral pipe runs. Because it is completely reusable, the fitting can be easily undone and reconfigured whenever you need to service or expand your system.
