Shurflo Twist-On Inline Pump Strainer | 255-213 | 1/2" NPSM

Protect your Shurflo RV water pump from debris-induced failure with the Shurflo 255-213 Twist-On Inline Strainer. This inlet-side filter screws directly onto the pump head — catching debris before it reaches internal pump components. The transparent bowl lets you see at a glance when it's time to clean.

What This Strainer Does

• Filters incoming water before it reaches the pump
• 50 mesh stainless steel screen catches dust, sand, and particulates
• Transparent filter bowl — visually monitor debris accumulation without disassembly
• Prevents premature pump failure from contaminated freshwater supply

Screws Directly on Pump Head

The 255-213 is designed to screw directly onto the Shurflo pump head — no separate mounting or plumbing routing required. Twist-on installation and removal for tool-free cleaning.

Easy Disassembly and Cleaning

When debris accumulates in the transparent bowl:

• Twist off the strainer
• Disassemble the bowl
• Rinse the 50 mesh stainless steel screen
• Reassemble and reinstall

No specialized tools required — routine cleaning takes just a few minutes.

⚠️ NPSM Thread — NOT NPTF Tapered

Critical fitment detail: the 255-213 uses 1/2" NPSM (American Standard Straight Mechanical Pipe) threading — NOT NPTF (American Standard Pipe Thread Tapered / Dryseal). These are different thread standards and are NOT interchangeable. Verify your pump's inlet thread type before ordering.
