Groco FTH-Series Bronze Flush Mount Thru-Hull Fitting (With Lock Nut)

Features:

• Groco FTH-Series Bronze Flush Mount Thru-Hull Fitting (With Lock Nut)
• Applications: Groco Seacocks or any similar product with NPS female threads
• Diameter: 3/4"
• These thru-hull fittings can also be used with NPT (tapered) threads in low pressure installations only
  • When connecting to tapered threads, a generous amount of pipe sealant or PTFE thread tape is absolutely required.
• Groco thru-hulls are the best choice for below the waterline installations
• They come complete with a bronze locknut with a bonding screw, or threaded directly into a Groco compatible seacock
• FTH Series Drip Control Bronze Thru Hulls can be used in a Flush mount or Drip-Control mount
  • In above waterline drain applications, choose between a drip control installation and a flush mount installation
    • In the drip control installation, the fitting protrudes slightly from the hull
    • As water flow through the fitting ceases, the last drops fall cleanly from the tapered edge of the fitting
  • In the flush installation, a cleaner profile is obtained, but if the installation is above the waterline, unsightly stains are likely to appear over time between the fitting and the waterline
    • The flush installation is, however, ideal for below waterline installations where the serious sailor wishes to reduce drag
