ASCO 8210G009 → ODE 21WN5KB190 crossover: same pipe size isn’t enough
A 3/4" pipe thread match is only the first check. Replacing an ASCO 8210G009 with an ODE 21WN5KB190 may work—only after you confirm thread standard, coil voltage and connector, acting type, minimum ΔP, seals and approvals for the exact valve and coil SKUs.
