If your industry operates under extreme pressure or temperature, you already know — even the smallest leakage can lead to massive losses. That’s where RTJ gaskets come into play. Designed to provide leak-proof sealing in challenging environments, these metallic rings are trusted across oil, gas, and chemical industries worldwide.
Unifit Metalloys, a trusted RTJ gasket manufacturer in Indonesia, delivers world-class gaskets engineered with precision. We specialize in all grades — from Stainless Steel and Duplex to Nickel Alloys, Hastelloy, Titanium, and Tantalum — ensuring exceptional performance and corrosion resistance in every environment.
What is an RTJ Gasket?
An RTJ (Ring Type Joint) gasket is a precision-engineered metallic ring designed to create a tight, high-pressure seal between flanges. These gaskets are commonly used in the oil & gas, refinery, petrochemical, and offshore industries — where standard soft gaskets simply can’t withstand the stress.
How Do RTJ Gaskets Work?
When bolted between two flanges with matching grooves, an RTJ gasket deforms slightly under load, forming a metal-to-metal seal. This eliminates leaks even under high pressure, high temperature, or cyclic conditions — making it one of the most reliable sealing solutions available.
As a trusted RTJ Gasket Manufacturer in Indonesia, Unifit Metalloys designs each gasket to meet global pressure and temperature standards, ensuring zero leakage and unmatched reliability.
Why RTJ Gaskets Are Essential for High-Pressure Applications
In industries like oil & gas or power generation, failure isn’t an option. RTJ gaskets can handle pressures up to 20,000 psi and temperatures above 1000°C. As a leading RTJ Gasket Manufacturer in indonesia, Unifit Metalloys ensures every gasket is engineered to deliver maximum sealing integrity under extreme operating conditions. That’s why their gaskets are trusted for critical joints in pipelines, reactors, and heat exchangers across Indonesia and global markets.
Being a leading RTJ Gasket Manufacturer in Indonesia, Unifit Metalloys delivers products that guarantee safe and long-lasting performance in extreme industrial conditions.
Material Grades & Metallurgies Used in RTJ Gaskets
Unifit Metalloys — a reputed RTJ Gasket Manufacturer in Indonesia — produces gaskets in multiple grades like Stainless Steel, Duplex, Inconel, Monel, and Hastelloy to cater to diverse industries.
| Material Type | Grades | Key Features |
|---|---|---|
| Stainless Steel | 304, 304L, 316, 316L, 321, 347 | Corrosion-resistant, ideal for general industrial use |
| Duplex & Super Duplex | UNS S31803, S32205, S32750, S32760 | High strength, excellent resistance to chloride stress cracking |
| Nickel Alloys | Inconel 600, 625, 718 / Incoloy 800, 825 | Excellent oxidation and corrosion resistance at high temperatures |
| Monel | 400, K500 | Perfect for marine and chemical applications |
| Hastelloy | C22, C276, B2 | Resistant to strong acids, oxidizers, and harsh chemicals |
| Titanium | Gr.2, Gr.5 | Lightweight, corrosion-resistant, perfect for chlorinated media |
| Tantalum | R05200 | Exceptional resistance to strong acids and high temperature |
Stainless Steel RTJ Gaskets
Stainless steel RTJ gaskets are the most widely used due to their strength and resistance to rust and scaling. Available in 304, 316, 321, and 347 grades, they are ideal for refineries and process plants. These gaskets are durable, cost-effective, and suitable for moderate corrosive conditions.
Duplex and Super Duplex RTJ Gaskets
When your operation faces chloride-rich environments, Duplex and Super Duplex RTJ gaskets are the best choice. Their dual-phase microstructure offers superior mechanical strength and resistance to pitting and crevice corrosion. Unifit Metalloys exports large quantities of Duplex RTJ gaskets to offshore projects across Indonesia.
Inconel & Incoloy RTJ Gaskets
Inconel 625 and 718 RTJ gaskets are built for high-temperature and high-pressure environments, such as gas turbines or chemical reactors. Incoloy 825, on the other hand, offers outstanding performance in sulfuric and phosphoric acid environments. These gaskets are preferred in power plants and acid-processing industries.
Monel RTJ Gaskets
If you’re working in marine or saltwater environments, Monel RTJ gaskets (Monel 400 & K500) are unbeatable. They resist seawater corrosion and are used in desalination plants, marine pipelines, and offshore platforms.
Hastelloy RTJ Gaskets
Known for their exceptional resistance to oxidizers and strong acids, Hastelloy C22 and C276 RTJ gaskets are widely used in chemical and fertilizer industries. They can handle nitric acid, hydrochloric acid, and sulfuric acid environments with ease.
Titanium & Tantalum RTJ Gaskets
For industries handling chlorinated or acidic solutions, Titanium (Gr.2/Gr.5) and Tantalum RTJ gaskets are ideal. Titanium provides strength and corrosion resistance, while Tantalum offers unmatched chemical stability — making these metals perfect for chemical reactors, evaporators, and condensers.
