Replacement portlight gasket. Gaskets are made of water resistant, thermo-plastic neoprene material. Neoprene gaskets have excellent strength, durability, are abrasion resistance, gaskets resist hardening, and remain soft and pliable, holding up under both hot and cold extremes.
To calculate your required length:
- Measure your cut-out circumference in inches
- Divide the number of inches you measured by 12
- Take that number, round up to the nearest whole number
Please be sure to give yourself a couple inches longer than your cut-out circumference as these gaskets are not shipped pre-cut to your size deck hatch!
For installation directions, please refer to Man Ship’s guide which can be found here.
