Product Overview

The Irritrol R-1308 is a replacement diaphragm for compatible 1-inch Irritrol 100 Series Century Plus valves, including the standard 100P1 configuration. It replaces the internal flexible sealing component when wear, debris, or damage causes leaking, incomplete shutoff, or unreliable valve operation.

Key Features

  • Genuine Irritrol replacement diaphragm
  • Designed for compatible 1-inch 100 Series valves
  • Supports 100P1 repair applications
  • Valve body, bonnet, solenoid, and regulator not included

Compatibility and Installation Notes

Confirm the valve size and model before ordering. The 1-1/2-inch, 2-inch, and 3-inch 100 Series valves use different diaphragms. Shut off water and controller power, relieve pressure, clean the valve interior, and inspect the seat and bonnet before reassembly.

Frequently Asked Questions

Will R-1308 fit a 100P1.5 valve?

No. The 1-1/2-inch valve uses R-1310.

Does it include a complete valve?

No. It is the replacement diaphragm only.

Why Buy Irritrol R-1308 from Big Frog Supply?

The exact 1-inch 100 Series application is identified so you can avoid mixing it with the larger R-1310, R934501, or R935001 diaphragms.
