Sealants & Torque Seal

Sealants and torque‑marking products play a vital role in aircraft maintenance, ensuring components remain secure, protected, and leak‑free under demanding operating conditions. This collection brings together a comprehensive range of aviation‑grade sealants, corrosion inhibitors, threadlockers, and torque‑marking compounds used by engineers, maintainers, and aircraft owners across New Zealand. Each product is selected for reliability, certification, and compatibility with common GA and commercial aircraft.

Our torque‑marking range includes multiple colours of Dykem Cross‑Check Tamper Proof Torque Mark, allowing maintainers to visually confirm fastener movement during inspections. These bright, high‑visibility compounds are widely used on engine components, control systems, and airframe hardware to detect loosening caused by vibration or thermal cycling.

For sealing and bonding tasks, we stock Dow Corning DOWSIL RTV 732 in clear and white, providing a versatile, multi‑purpose silicone sealant suitable for access panels, avionics installations, and general airframe use. For high‑temperature environments such as engine bays, DOWSIL RTV 736 Red offers enhanced heat resistance and long‑term durability. These products are trusted for their strong adhesion, flexibility, and resistance to weathering.

Our corrosion‑inhibitive options include Tectyl 891D and PPG/PRC DeSoto aerospace sealants, designed to protect metal surfaces from moisture, salt, and environmental exposure. These compounds are essential for long‑term airframe preservation, especially in coastal or humid operating environments. We also carry PRC Class B access‑door sealants, ideal for sealing inspection panels and preventing moisture ingress.

For threadlocking and component protection, Loctite 222 Low Strength Threadlocker provides secure retention for small fasteners without risking damage during removal. Dupont Molykote 4 Electrical Insulating Compound supports electrical system reliability by sealing and protecting connectors from moisture and contamination.

To support clean, precise application and removal, our collection includes sealant scrapers in multiple sizes, helping maintainers remove old sealant without damaging surrounding surfaces.

Every product in this collection meets aviation performance standards and manufacturer requirements, giving engineers confidence in long‑term reliability and airworthiness. Whether you’re sealing an access panel, marking critical fasteners, applying corrosion protection, or performing routine maintenance, Pilot Shop provides trusted sealants and torque‑marking products backed by fast local shipping and knowledgeable support.
