Frequently Asked Questions
Match the rod to your pump assembly (e.g., 16X428, 17H828, 253056) and confirm your sprayer is a TexSpray Mark IV (Standard or Premium). If unsure, check the illustrated parts list for your exact model/serial.
Chromex is a hardened, wear-resistant surface treatment that improves durability against abrasion and extends the service life of the rod under high-pressure operation.
It’s highly recommended. Worn packings/seals can cause pressure loss and premature wear on a new rod. Replacing them during rod service restores full pump efficiency and reliability.
Scoring on the rod, pressure fluctuation, reduced output, leakage past packings, or excessive pump noise are common indicators the rod (and packings) need service.
