Getsun High Temperature RTV Silicone Gasket Maker Manufacturer
The Professional-Grade RTV Silicone Gasket Maker Built for Extreme Conditions
When a standard sealant fails under pressure and heat, GETSUN high temperature RTV silicone steps in — engineered with Dow Corning silicone polymer from the USA, trusted by automotive professionals worldwide.

GETSUN High Temperature RTV Silicone Instant Gasket
Formulated on the technical foundation of Germany's automotive repair standards, GETSUN's RTV silicone gasket maker offers an industrial-strength solution for sealing critical engine components. The sealant leverages low-volatile silicone polymer sourced from Dow Corning USA to deliver a flexible, pressure-resistant seal that outlasts conventional gasket materials.
Whether applied as a water pump sealant or used to seal valve covers and exhaust manifolds, this product remains structurally intact through thousands of thermal cycles — without cracking, shrinking, or migrating.
Core Technical Features
Six engineering advantages that define the GETSUN high temperature RTV silicone performance profile.
Extreme Temperature Resistance
Rated for continuous use from -76°F to 580°F (-60°C to 304°C) intermittent, this high temperature RTV silicone maintains its seal even through aggressive heat cycling near exhaust manifolds and turbocharger components.
Skin Dry in 15 Minutes
The sealant forms a surface skin in just 15 minutes, allowing assembly to proceed quickly in time-sensitive repair workflows. Full cure completes within 24 hours for maximum bond strength.
Leak-Proof Sealing
Creates a gasket-grade seal in seconds with resistance to oil, coolant, and pressure. As a water pump sealant, it prevents coolant leakage even under the vibration and thermal stress typical of high-load engine operation.
Pressure Resistant Formula
Engineered with a silicone polymer matrix sourced from Dow Corning USA, the RTV silicone gasket maker resists deformation under high mechanical and fluid pressure — a critical requirement for intake manifolds and timing covers.
No Cracking or Shrinkage
Unlike conventional anaerobic or paper gaskets that harden and crack over time, GETSUN high temperature RTV silicone remains permanently flexible, preventing gaps that lead to leaks and costly engine damage.
Low Volatile Composition
The low-volatile formulation reduces off-gassing during curing, making it suitable for use in enclosed engine bays and in applications near oxygen sensors — where standard silicones can cause sensor contamination.
The Problems GETSUN Solves
Understanding the real challenges automotive professionals and procurement managers face in the field.
Gaskets That Fail Under Heat
Standard sealants degrade rapidly at temperatures above 300°F, common in performance engines. The GETSUN RTV silicone gasket maker handles sustained heat up to 580°F intermittently without bond degradation.
Repeated Coolant Leaks at Water Pumps
Water pump gasket failures are among the most frequent causes of engine overheating. As a reliable water pump sealant, GETSUN forms a coolant-tight bond that resists the constant temperature fluctuations in the cooling circuit.
Rigid Seals That Crack Over Time
Rigid compounds become brittle with thermal cycling, causing micro-cracks and eventual leaks. GETSUN high temperature RTV silicone stays flexible at all temperatures, ensuring long-term sealing integrity.
Slow Curing Delays Workshop Output
Long cure windows mean vehicles sit idle on lifts longer than necessary. GETSUN skin dries in 15 minutes, letting technicians move to the next step quickly and return the vehicle to service within 24 hours.
Supplier Inconsistency and Quality Risks
B2B buyers sourcing sealants at volume face inconsistent product quality. GETSUN is packaged in standardized 85g units, 144 pieces per carton, providing consistent specification and traceable quality for bulk procurement.
Sensor Contamination from Standard Silicone
High-acetic-acid silicones can damage oxygen sensors in modern engines. GETSUN's low-volatile RTV silicone gasket maker is formulated to minimize this risk while delivering full engine sealing performance.
When Is This Product the Right Choice?
GETSUN high temperature RTV silicone is the professional answer for the following applications and scenarios.
Acts as the primary water pump sealant where OEM gaskets are unavailable or worn.
Seals valve cover perimeters against oil leaks — an extremely common wear point in higher-mileage engines.
Withstands the sustained high temperatures produced by exhaust gases at the manifold-to-head interface.
Prevents oil leaks at the oil pan rail — a frequent failure point in engines with aging original gaskets.
Ideal where the temperature range of the cooling system demands flexibility and coolant resistance.
Provides a reliable seal at intake manifold runners subject to vacuum and thermal cycles.
Creates a durable, leak-proof perimeter seal where oil circulation meets external cover faces.
Packed at 144 pcs/ctn, GETSUN is structured for workshop, fleet, or distributor procurement at volume.

Application Instructions
Follow these steps for a professional, leak-proof result every time.
-
1Surface Preparation Clean and dry all mating surfaces completely. Remove all dirt, grease, and old gasket material using a residue-free solvent. The cleaner the surface, the stronger the final seal.
-
2Open the Tube Remove the cap, puncture the inner foil seal, and attach the nozzle. Trim the nozzle tip to the desired bead size to suit the specific gap being sealed.
-
3Apply the Sealant Apply an even bead of high temperature RTV silicone around the full perimeter of one mating surface, maintaining consistent bead diameter throughout. Avoid gaps or overlaps in the bead.
-
4Allow Surface Skin to Form Under typical conditions, the RTV silicone gasket maker will skin dry in approximately 15 minutes. Wait for this skin to form before assembling the parts together.
-
5Assemble and Cure Bring the mating surfaces together once the silicone has skinned. Torque fasteners to the manufacturer's specification. Allow a full 24 hours for complete cure before operating the vehicle or pressurizing the system.
-
6Clean Up and Store Trim any excess cured silicone with a clean knife. Clean the nozzle tip and replace the cap tightly after use. If silicone has cured inside the nozzle, remove the plug with a pin or paper clip before the next application.
Safety and Usage Notes
Uncured sealant may cause skin and eye irritation — avoid direct contact. If contact occurs, flush eyes with water and remove from skin with a dry cloth; consult a physician if irritation persists. Use only in well-ventilated areas. This water pump sealant and general RTV silicone gasket maker is not recommended for continuous immersion in gasoline, and should not be used as a substitute for cylinder head gaskets where predetermined tolerances are required.
