This manual provides essential information for the safe and effective use of RectorSeal No. 5 Pipe Thread Sealant.
2. Product Overview
Figure 1: RectorSeal No. 5 Pipe Thread Sealant (1.75 oz tube).
RectorSeal No. 5 is suitable for a wide range of pipe materials, including galvanized steel, iron, brass, copper, aluminum, stainless steel, polyethylene, reinforced fiberglass, and PVC. It is important to note that this product should NOT be used on ABS or CPVC piping.
Key features include:
- Non-hardening and slow-drying formula.
- Seals, lubricates, and protects threaded pipe and fittings.
- Lead-free and contains no metals.
- Permits easy breakout without thread damage.
- Suitable for natural gas and water lines up to 2 inches and pressure up to 100 psi for immediate service. Other services require 24 hours after application.
3. Safety Information
Always read and understand the product label before use. Wear appropriate personal protective equipment, such as gloves and eye protection, during application. Ensure adequate ventilation in the work area.
WARNING: Combustible liquid. Keep away from heat, sparks, and open flames. Avoid prolonged contact with skin and eyes. In case of contact, flush with water. If swallowed, do not induce vomiting; seek immediate medical attention.
4. Setup and Application
4.1. Preparation
- Ensure all pipe threads are clean and free from dirt, grease, or old sealant residue.
- Confirm the pipe material is compatible with RectorSeal No. 5 (e.g., galvanized steel, iron, brass, copper, aluminum, stainless steel, polyethylene, reinforced fiberglass, PVC). Do not use on ABS or CPVC.
- Shake the tube well before use to ensure consistent product mixture.
4.2. Application Steps
- Apply a uniform coat of RectorSeal No. 5 to the male pipe threads. Ensure complete coverage of the threads, leaving the first two threads bare to prevent excess sealant from entering the pipe system.
- Assemble the pipe joint by hand-tightening, then use a wrench to tighten to the recommended torque for the specific pipe and fitting type.
- For natural gas and water lines up to 2 inches and pressure up to 100 psi, the piping system may be placed into immediate service. For other services, it is recommended to wait 24 hours after application to allow for proper setting.

6. Maintenance
Once applied and cured, RectorSeal No. 5 requires no specific maintenance. Periodically inspect sealed joints for any signs of leakage, especially in critical applications. The sealant's soft-set nature allows for easy disassembly and reapplication if future maintenance or repairs are needed.
Store the product in its original container in a cool, dry place, away from direct sunlight and sources of ignition. Ensure the cap is tightly sealed after each use to prevent drying out.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Leakage after application | Insufficient sealant applied, improper thread cleaning, incorrect pipe material, insufficient cure time (for non-immediate service applications). | Disassemble joint, clean threads thoroughly, reapply sealant ensuring full coverage, reassemble and allow adequate cure time if necessary. Verify pipe material compatibility. |
| Sealant drying out in tube | Cap not sealed tightly, improper storage. | Ensure cap is tightly sealed after each use. Store in a cool, dry place. |
| Difficulty breaking out joint | Not applicable, RectorSeal No. 5 is designed for easy breakout without galling or seizing threads. | Use appropriate tools for disassembly. The sealant itself should not cause difficulty. |
