Description

When you’re out spraying and notice your boom pressure isn’t holding steady anymore, there’s a good chance the diaphragm in your 144A regulator has given up the ghost. These rubber diaphragms take a beating from constant pressure cycling and chemical exposure, but the good news is they’re designed to be replaced rather than forcing you to buy a whole new regulator.

What You’re Getting

Made from EPDM rubber that stands up to agricultural chemicals and temperature swings
Direct replacement that restores proper pressure regulation to your spray system
Comes as a set of 2 diaphragms since your 144A regulator needs both to work properly
Engineered to the same specs as the original TeeJet part for reliable performance

Built for Real Farm Work

The 144A is a workhorse regulator you’ll find on spray booms across all kinds of farming operations. Whether you’re running a pull-type sprayer behind your utility tractor or have a self-propelled unit covering hundreds of acres, this diaphragm keeps your spray pressure right where you need it for consistent application rates.

Made to Last

EPDM rubber construction handles the harsh conditions that come with agricultural spraying. It won’t crack from sun exposure like some cheaper materials, and it holds up to the chemical cocktails you’re putting through your system day after day.

Good to Know

Before you tear into your regulator, make sure to relieve all pressure from the system and have a clean workspace ready. The old diaphragms might be stuck or brittle, so take your time removing them. A little silicone spray on the new ones makes installation easier and helps them seat properly.
