Tax included. Shipping calculated at checkout.
Seal Grade

Mechanical Seal Kit suits all SpaNET Jetmaster, Davey QB series, LX Whirlpool pumps. Come in 2x grades. Standard & Superior. Standard seals are far better than older LX Whirlpool seals. 

Spring Section: OD of Rubber: 41.5mm / ID: 17.4mm
Ceramic Section: OD of Rubber: 35.5mm / ID of Ceramic: 18.95mm

Standard-Grade Seals:

  • Viton elastomers, with carbon face, and ceramic base. Note that these seals are still far superior to the low-grade seals found in older LX pumps, and current gray-market imports. 

Superior-Grade Seals:

  • Silicon Carbide primary ring / Silicon Carbide seat seal surfaces with Viton elastomers and stainless steel hardware for superior longevity against abrasion, corrosion & chemicals, and dry running - far more resistant to corrosives in the water.
