Who hasn’t experienced it? You’re in the middle of repairing your car, and a stubborn hemp fitting gets in your way. But before frustration and despair set in, there are some proven methods and helpful tips to loosen even stuck hemp fittings without damaging the components.
Why Are Hemp Fittings Sometimes So Stubborn?
Hemp has long been used as a sealant in plumbing and heating, but also in the automotive industry. In combination with sealing paste, the hemp gasket provides reliable sealing for threaded connections, for example, on oil lines or water pumps.
But what sometimes makes hemp fittings so difficult to loosen?
- Bonded Sealing Compound: Over time, the sealing paste and hemp can bond together and literally stick.
- Corrosion: Rust formation on the threads can further seize the fitting.
- Overtightening: If the fitting was tightened too much last time, loosening it can be a real challenge.
Loosening Hemp Fittings: Step-by-Step Guide
Don’t worry, with the right approach, any hemp fitting can be loosened.
- Preparation is Key: Before you start loosening, you should protect the surrounding areas as much as possible. Cover sensitive parts to protect them from damage or contamination.
- Rust Penetrant – A True Helper: Apply rust penetrant generously to the fitting and let it soak in for a while. The rust penetrant creeps into the threads and loosens seized connections.
- The Right Leverage: To loosen the hemp fitting, use a suitable wrench or box-end wrench. It is important that the wrench sits firmly on the fitting to avoid slipping.
- With Feel and Patience: Now try to turn the fitting counter-clockwise. Don’t use too much force, as this can lead to damage. If the fitting doesn’t loosen immediately, repeat the steps with the rust penetrant and try again.
- Heat Can Help: In stubborn cases, heat can help loosen the bonded sealing compound. Carefully heat the fitting with a heat gun or a blowtorch. However, be extremely careful and observe safety precautions!
