Raypak 185/207A/206A/R185A/R185B Bypass Spring (006718F) poolparts Features a 13/16 inch stemThe Raypak bypass spring is designed for compatible 185, 207A, 206A, R185A, and R185B heater applications where the supported bypass assembly needs a new spring. A spring like this is useful because it helps the bypass mechanism move and respond the way the heater was designed to operate, contributing to steadier internal flow behavior. This replacement is especially useful when the original spring has weakened, broken, corroded, or gone missing
