Dimension One 3/8" Straining Barb Adapter SS 6540-171
Dimension One 3/8" Straining Barb Adapter SS (6540-171) is your go-to fix for secure, leak-free hose connections in spa pumps. Crafted from durable stainless steel, this compact adapter filters debris while ensuring smooth water flow—perfect for keeping your system running reliably. This OEM-quality adapter threads into Sundance/Dimension One pumps (2000+ models), converting a 1/4" MIPT inlet to a 3/8" barb outlet for hoses. It replaces plastic versions with corrosion-resistant steel, often paired with O-ring 6540-263 for a tight seal.
