Netafim - Techline 17mm Check Valve Dripline - Blank Tubing 250'

Techline DL Dripline offers maximum uniformity for both subsurface and on-surface irrigation applications. Ideal for professional installations across turf, slopes, and high-traffic areas, its pressure-compensating emitters and anti-siphon design ensure efficient watering with reduced maintenance. With a flexible, UV-resistant build and innovative emitter design, it's perfect for projects demanding reliability, precision, and eco-conscious performance.

Key Features & Benefits:

• Pressure-compensating emitters deliver uniform flow over a wide pressure range (14.5–58 PSI)
• Anti-siphon diaphragm prevents vacuum-related debris ingestion
• Emitters feature continuous self-flushing and a root-resistant raised outlet design
• 2 PSI check valve in each emitter eliminates low-head drainage; holds back up to 4.6’ of water
• Broad range of flow rates (.26, .4, .6, .9 GPH) and emitter spacings (12”, 18”, 24”)

Construction & Durability:

• Flexible tubing with UV-resistant polyethylene construction withstands heat and direct sunlight
• Self-contained, one-piece dripline ensures long-term reliability and easy installation
• Qualifies for LEED projects with post-consumer and post-industrial recycled material

Ease of Installation & Use:

• Highly flexible tubing curves to a 7" radius for tight or irregular landscapes
• Can be buried up to 6" deep or installed on-surface under mulch
• No need for air/vacuum relief vents or automatic flush valves in subsurface installs
• Compatible with Techline fittings, 700 Series compression, or ½” poly insert with clamps
