⚠️ IMPORTANT: BUYER'S GUIDE (TECHNICAL VERIFICATION)
PORT CONFIGURATION: Confirm your original valve has the same arrangement: one Blue L-shaped port and two brown straight ports.
PIN ALIGNMENT: This block uses two parallel metal pins for mounting. Ensure your seat's internal frame is clear of debris before sliding the new valve in.
AIR LINE INTEGRITY: Before installation, check your air lines for cracks or moisture. Moisture is the leading cause of internal valve corrosion in ISRI seats.
