Categories: Oil plug plug series
In high-pressure industrial applications, the hex flange oil plug represents a significant advancement in sealing technology. This innovative component combines a hexagonal drive head with an integrated flange base, creating a dual-sealing mechanism that outperforms conventional oil plugs. Engineered for extreme conditions, our ISO 9001-certified hex flange oil plug delivers 50% better leak prevention and 30% longer service life compared to standard designs. The unique flange distributes torque evenly during installation, eliminating thread stripping while providing a secondary sealing surface—making it the optimal choice for critical oil and hydraulic systems.
Dual-Sealing Flange Design: The integrated flange on this hex flange oil plug creates an additional compression seal against the mounting surface. This dual-barrier system prevents leakage even at pressures exceeding 500 PSI, outperforming single-seal designs by 2:1.
Enhanced Torque Distribution: Unlike traditional plugs, the flange base of the hex flange oil plug evenly distributes installation force. This prevents housing damage in soft metals like aluminum, reducing equipment failure rates by 45%.
Corrosion-Resistant Construction: Manufactured from Grade 316 stainless steel or brass with nickel plating, our hex flange oil plugs withstand salt spray (ASTM B117), chemicals, and temperatures from -50°C to 200°C.
Quick-Install Hex Head: The six-sided head accepts standard wrenches, allowing one-tool installation in confined spaces. Anti-slip knurling ensures secure grip, cutting maintenance time by 60%.
The hex flange oil plug excels where standard plugs fail:
Heavy Machinery: In hydraulic excavators and presses, the flange design maintains seal integrity under constant vibration, preventing costly fluid loss in Caterpillar and Komatsu equipment.
Marine Engineering: Saltwater-resistant hex flange oil plugs with zinc-nickel coating protect ship engines and offshore rig systems, certified to NACE 17-1 standards.
Aerospace: FAA-approved variants feature lightweight titanium construction, ensuring fuel system security in aircraft at altitudes over 30,000 feet.
Renewable Energy: Wind turbine gearboxes utilize hex flange oil plugs to withstand torque fluctuations and temperature extremes in Arctic installations.

Q1: Do you provide international delivery services? Are there additional fees?
A1: Yes, we offer international delivery services, typically in cooperation with international couriers like DHL and UPS. In addition to basic freight charges, carriers may charge a “holiday surcharge” during peak business seasons (e.g., October to next January). Specific fees depend on the destination, cargo weight, and volume, and need to be calculated accordingly.
Q2: If the product does not meet my needs, what is your return, exchange, or warranty policy?
A2: Our core principle is: for issues truly due to product quality defects or incorrect specifications shipped, we provide return, exchange, or repair services. Specific process: Please inspect the goods promptly upon receipt. If there are problems, contact us immediately and provide evidence. After both parties verify the cause, if it is confirmed to be our responsibility, we will cover the freight costs and arrange for reshipment or repair. The specific warranty period (e.g., 12 or 24 months) will be clearly stated in the contract.
Q3: How can I quickly confirm if a plug is compatible with my equipment model?
A3: To ensure a perfect match, we suggest you provide the equipment model, brand, clear photos of the original plug, and key parameters such as thread specification, sealing form, working pressure, and temperature. Our engineers will verify this and can provide sample testing upon request.
Q4: Is there a tiered pricing structure for purchasing plugs? Can large orders apply for exclusive discounts?
A4: Yes, we support tiered pricing, where the unit price becomes more favorable with larger purchase volumes. For long-term stable or large orders, we are also very willing to negotiate exclusive discounts. Please provide your estimated annual purchase volume or single order quantity so we can provide an accurate quote.
Q5: What convenient payment methods do you support? How does corporate bank transfer work?
A5: We support multiple payment methods:
Common methods: Telegraphic Transfer (T/T), Letter of Credit (L/C).
Corporate bank transfer: You can operate through your corporate online banking, accurately fill in our receive payment information, and complete the transaction using tools like U-shields.
Third-party payments: Such as PayPal, suitable for small trial orders.
Q6: How long after placing an order will it be shipped? Can urgent needs be expedited?
A6: After receiving full payment, we usually arrange shipment within 3-7 working days. For urgent needs, we can coordinate expedited production and priority logistics (such as air freight), but this will incur additional costs. Please communicate with us in advance.
Q7: If the received specifications are incorrect or there are quality issues, how will it be handled?
A7: Before communication, we will first confirm the drawings with you. After drawing confirmation, we will send you a sample. Once the sample is verified, we will proceed with mass production.
Q8: Can you produce any product?
A8: Yes, any type of any material. As long as you provide drawings, we can customize according to your requirements.
