Stainless Steel Vent Protector – 1/4 in. MNPT Thread (SVP-4N)

The SVP-4N is a 1/4" MNPT vent protector built for high-purity and industrial systems requiring safe gas venting, port protection, or pressure relief. Made from 316 stainless steel, it resists corrosion and environmental exposure while offering secure thread engagement through its precision-tapered design.

Commonly used to cap off manifolds, valves, and instrumentation panels, the SVP-4N ensures open ports are shielded from debris, insects, and external contamination. It’s ideal for systems where pressure must be safely vented, and cleanliness is non-negotiable—such as CIP (Clean-in-Place) loops, sanitary assemblies, or compressed gas distribution panels.

This part can also serve as a 1/4" bug screen or mud dauber, providing extra protection for exposed ports in harsh or outdoor installations.

Key Benefits

• Protection: Shields ports from insects, debris, and environmental contaminants
• Pressure Relief: Supports clean venting in pressurized systems
• Durability: 316 stainless body resists chemicals, pressure, and wear
• Compatibility: Fits standard 1/4" NPT ports with leak-tight engagement
• Versatility: Works in lab, skid, cleanroom, and industrial setups

Typical Applications

• Pressure relief vents on manifolds and valve blocks
• Clean-in-place (CIP) instrumentation systems
• Hygienic stainless steel valve and port protection
• Lab setups, gas panels, and OEM instrumentation
