Product Description
Product Details
1. Complete 8-Piece Stack Set
Includes male adapters, female adapters, and multiple V-shaped chevron rings, allowing proper stacking configuration for optimal plunger sealing in TU26 pumps.
2. Progressive Sealing Action
Individual V-rings expand radially under pressure, creating tighter contact with both plunger and cylinder wall as pressure increases - unlike standard O-rings.
3. Chemical-Resistant Material Options
Available in NBR (oil/water), Viton (solvents/chemicals), PTFE (high-temp/aggressive), or leather (legacy/compatible) to match your specific spray media requirements.

FAQ
Q1: What is a V-packing set used for in a TU26 sprayer pump?
A: V-packing seals (chevron rings) surround the pump plunger, creating a high-pressure dynamic seal that prevents spray fluid from leaking past the plunger during the compression stroke.
Q2: How do I install the 8 V-packing rings correctly?
A: Stack the rings in alternating orientation (male and female adapters at ends, V-rings facing toward pressure side). Typically, the open side of each V-ring faces the high-pressure direction. Refer to your pump manual for exact sequence.
Q3: How do I know if my V-packing set needs replacement?
A: Signs include fluid leaking from the front of the pump housing, reduced spray pressure, the pump running but failing to build pressure, or visible wear/cracking on the rings when disassembled.
