The wet end seal or shaft seal, as the name suggests, provides a seal between the hydraulic and electrical parts of a spa pump. It is therefore placed between the shaft and the pump body to prevent water leakage.

Be careful, a leak of the wet end seal can easily be mistaken with a leak of the pump union or the seal, as these parts should also be changed when worn out.

With the right tools, replacing this part is not complicated and above all, it does not require the assistance of a professional. Our team will advise you and explain what steps to take to replace your spa pump wet end seal in a video !
