Rain Bird PC18 Pressure-Compensating Module - 18 GPH

The Rain Bird PC18 is a compact, pressure-compensating drip module that delivers a steady 18 gallons per hour for medium-flow point irrigation. Engineered for larger shrubs, trees, and other landscape zones that require consistent watering, the PC18 maintains uniform output across varying supply pressures to reduce run-to-run variation and improve plant health.

• Consistent flow: 18 GPH pressure-compensating output across 10-50 psi (0.7 to 3.5 bar).
• Quick installation: Self-piercing barbs allow one-step insertion into 1/2 inch or 3/4 inch drip tubing using a Xeriman tool; no pre-punching required.
• Durable construction: UV-resistant, color-coded plastic helps identify flow rate and withstands outdoor conditions.
• Barb inlet: Standard barb connection for retrofit and new installations; connects directly to 1/2 inch or 3/4 inch tubing.
• Clog protection: Designed for use with 100-mesh (150-micron) filtration to reduce debris-related blockage.
• Endpoint use: When used as the final emitter, attach a PC Diffuser Cap (X50001 or X50002) to prevent squirting.

Compact and unobtrusive, the PC18 is ideal for landscape and commercial irrigation systems that need reliable, low-maintenance medium-flow emitters. Note: some suppliers sell PC modules in minimum pack quantities; confirm ordering multiples before purchase.
