What Is Silicone Grease?
Silicone grease is a non-curing lubricating and sealing grease made from silicone oil(most commonly polydimethylsiloxane/PDMS) with suitable thickeners(typically amorphous fumed silica) and additives. It is commonly used where rubber, plastic, metal, O-rings, valves, electrical connectors or sealing components need moisture resistance, electrical insulation, smooth assembly or long-term protection.
Key Characteristics & Benefits：
Waterproof
Protects against moisture, preventing rust and corrosion.
Sealing
Forms a durable barrier to keep out dirt, dust, and contaminants.
Dielectric
Highly insulating properties prevent electrical arcing and short circuits in automotive and electronic connections.
Lubricating
Reduces friction and wear on moving parts for smooth operation.
Anti-Corrosion
Shields metal surfaces from corrosive elements and harsh environments.
Anti-Oxidation
Prevents degradation and extends the lifespan of components exposed to air.
Material Safe
Unlike petroleum-based greases, it will not swell, dry out, or degrade rubber and plastic.
Extreme Temp.
Retains its consistency and lubricating properties across a massive temperature range (typically -40°F to 500°F).
Common Problems Silicone Grease Helps Solve
B2B buyers face specific challenges in assembly, maintenance and packaging. Here is how a matched silicone grease formulation addresses them.
O-rings get pinched during assembly
A suitable silicone grease helps seat O-rings smoothly and reduces assembly damage, ensuring a proper seal without tearing.
Valves become difficult to turn
Silicone grease can provide smooth movement for faucet valves, water valves and sealing parts while resisting water washout.
Connectors corrode in wet environments
Dielectric silicone grease helps seal out moisture around connectors and terminals, reducing the risk of tracking and corrosion.
Rubber parts swell with wrong lubricant
Petroleum-based products may degrade rubber. Silicone grease is often selected specifically for rubber and plastic compatibility.
Small packs leak during transport
B2B buyers need tubes, sachets and syringes with secure tail sealing that survive storage, shipping and retail handling.
One formula does not fit all
Different applications require different viscosity, NLGI grade, additive systems or food-grade status. Off-the-shelf options often fail.

Laboratory Testing Standards
Every batch undergoes rigorous evaluation to guarantee peak performance in demanding industrial applications.
Dynamic Pressure Sealing Test
Our silicone grease undergoes rigorous pressure testing to ensure zero leakage in dynamic and static environments. It maintains high structural stability, preventing fluid or gas bypass even under fluctuating pressure spikes in valves and vacuum systems.
Water Washout Resistance Test
A grease sample is placed in a ball bearing, installed in a housing with specific clearance, and rotated at a set speed. Water is sprayed to simulate washout conditions. The grease's resistance is tested by measuring the amount washed away.
Our silicone oil base with advanced thickeners ensures strong adhesion and waterproof protection.
Breakdown Voltage Test
Breakdown voltage testing evaluates the insulating properties of lubricating grease. It determines the voltage at which silicone grease fails, expressed in kilovolts (kV). An increasing alternating electric field is applied until breakdown occurs.
Our grease, tested for high dielectric strength (kV/mm), prevents electrical arcing, corona discharge, and tracking in high-voltage cable accessories and sensitive connectors.
Material Compatibility Test
Use a 2D measuring tool to compare silicone dimensions before and after applying grease. This helps assess silicone expansion and compatibility.
We check compatibility with plastics and rubbers (EPDM, NBR, Viton). Our grease ensures excellent O-ring lubrication without causing shrinkage, swelling, or hardening, preserving seal integrity.

Where Silicone Grease Is Used
Silicone grease is widely used in O-rings, rubber seals, plumbing valves, automotive electrical connectors, food equipment, plastic parts, and waterproof sealing applications.
O-rings and Rubber Seals
Used to lubricate and protect O-rings, gaskets, and rubber seals, helping reduce friction, prevent wear, and extend service life.
Plumbing and Valve Systems
Commonly applied to faucets, water valves, ball valves, pump seals, and plumbing fittings due to its good water resistance.
Electrical Components
Helps protect connectors, cable joints, switches, outdoor lighting, and low-voltage electrical parts from moisture and oxidation.
Automotive
Used as dielectric grease for spark plug boots, ignition coils, battery terminals, sensors, and wiring connectors to prevent moisture and corrosion.
Outdoor and Marine
Used for flashlight seals, diving equipment O-rings, fishing gear, zippers, and camping equipment where waterproof protection is needed.
Food Equipment
Food-grade option available for coffee machine brew units, ice maker, water filter&dispensers, food machinery seals, and beverage equipment.

How To Choose the Right Silicone Grease
Follow this simple decision path to find the right formulation and packaging for your project.
Step 1 — Identify the Material
Confirm whether the contact surface is rubber, plastic, metal, ceramic, glass or mixed materials.
Step 2 — Define the Function
Choose the main purpose: lubrication, sealing, moisture barrier, dielectric insulation, assembly aid or private-label kit use.
Step 3 — Operating Conditions
Review temperature, water exposure, chemical contact, speed, load and service interval.
Step 4 — Select Grease Type
- General-purpose for rubber assembly
- Dielectric for connector sealing
- Food-grade option for incidental contact
- PTFE-enhanced for smoother movement
- PFPE grease for extreme environments
Step 5 — Packaging & Docs
Choose the right tube, sachet, syringe, jar or pail, then confirm label, carton, MSDS, TDS and sample testing requirements.
Silicone Grease vs Lithium vs PTFE vs PFPE
Understanding the differences helps prevent material incompatibility and premature failure.
| Comparison Item | Silicone Grease | Lithium Grease | PTFE Grease | PFPE Grease |
|---|---|---|---|---|
| Base System | Silicone oil-based | Mineral/synthetic oil with lithium thickener | Synthetic/mineral/silicone base + PTFE | Perfluoropolyether base + PTFE thickener |
| Best For | Rubber, plastic, O-rings, valves, connectors | General metal lubrication and bearings | Low-friction sliding, selected plastic/metal | Vacuum, oxygen service, aggressive chemicals |
| Water Resistance | Good | Varies by grade | Good to very good | Very good |
| Rubber/Plastic | Often suitable, testing recommended | May not suit sensitive rubber/plastic | Depends on base oil | Generally strong, test required |
| Cost Level | Medium | Lower | Medium to higher | Higher |
| When To Choose | When sealing, moisture resistance and rubber compatibility matter | When general metal lubrication is the main need | When lower friction or smoother movement is required | When silicone cannot handle chemical, oxygen, vacuum or extreme temp |
Note: Silicone grease is not always the right lubricant. For heavy-load metal bearings or aggressive chemicals, Morelic may recommend PTFE grease, PFPE grease or anti-seize paste after reviewing the application.
When Silicone Grease May Not Be the Right Choice
Heavy-load metal bearings
A lithium complex, synthetic grease or other load-bearing grease is usually more suitable for high-friction metal-to-metal contact.
High vacuum or oxygen service
PFPE grease may be safer for demanding vacuum, oxygen or chemically aggressive environments.
Direct electrical contact surfaces
Dielectric silicone grease is insulating. It should be used around connectors for sealing, not as a conductor between metal contacts.
Surfaces requiring painting later
Silicone contamination can affect coating or adhesion. Confirm the manufacturing process before use.
Very high-temp continuous exposure
Confirm the continuous and peak temperature limits from the selected TDS before specifying silicone grease.
Unknown rubber or plastic material
While generally safe, compatibility testing is recommended before mass production or private-label launch on sensitive materials.
