Caleffi Na20760 1" mnpt, 1-1/4" nut, washer hydronic valve replacement part

Genuine Caleffi gasket, O-ring, or sealing washer for Caleffi valve and fitting assemblies. Replacement seals restore leak-free connections at union joints, valve bodies, and port connections.

🔌 Connection Type

NPT (National Pipe Tapered) — standard American tapered thread, requires thread sealant (PTFE tape or pipe dope)

🔍 What This Part Fixes

✖ Problem Symptoms

  • ✖ Leaking at union joint or port connection — O-ring or gasket compressed or damaged
  • ✖ Seal replacement required during valve service or cartridge replacement

✓ What This Restores

  • ✓ Genuine OEM seal — correct elastomer compound and dimensions for Caleffi components
  • ✓ Restores leak-free connection at valve body or union joint

🔧 Installation Overview

  1. Inspect all seals when disassembling — replace any that show compression set, cracking, or damage
  2. Lightly lubricate O-rings with silicone-compatible lubricant before assembly
  3. Do not overtighten union nuts — O-ring seals require only moderate torque
