Bilge pump line threads (connections for the pump discharge hose/fittings) operate under very low fluid pressure and are exposed to bilge water, oil, and cleaning chemicals. The primary requirement is a secure, water-tight seal against backflow. Since these pumps and hoses are often removed for cleaning or replacement, the sealant must provide a Low Strength bond to allow for easy, non-destructive disassembly.
INCURE ProGrip™ 209 Hydraulic & Pneumatic Thread Sealant
INCURE ProGrip™ 209 is designed for lower-pressure systems where serviceability and easy dismantling are key. This makes it the ideal functional Low Strength choice for bilge systems, ensuring a reliable, water-tight joint that is simple to service.
| Key Feature | Performance for Bilge Pump Line Threads |
| Functional Low Strength | Provides a secure, water-tight seal without seizing the joint. Allows for easy, non-destructive disassembly using hand tools when pump/hose replacement is needed. |
| Sealing Capability | Optimized for creating reliable seals in fluid lines, perfectly suited for sealing against low-head bilge water pressure. |
| Chemical Resistance | Good resistance to bilge fluids, including water, oil, and common cleaning agents. |
| Prevents Corrosion | Fills the thread gaps completely, preventing thread corrosion and thread lock-up in a damp environment. |
Application Steps: Sealing Bilge Pump Line Threads
For maximum reliability and ease of service, follow these steps:
- Preparation: Clean both the male and female threads thoroughly to remove all oil, grease, and contaminants from the bilge environment. Use an appropriate cleaner and wipe dry.
- Application: Apply a continuous, thin bead of ProGrip™ 209 around the male thread, skipping the first thread. Ensure full coverage over the engaged threads.
- Assembly: Immediately thread the fitting into the pump/port and tighten until the components are correctly positioned.
- Curing: Allow the sealant to cure for a minimum of 24 hours to reach full strength before pressurizing the line (or using the pump).
