Socket Cap
- Reliable and Leak-Proof Connection
- Easy Installation and Cost-Effective
- High Strength and Durability

High Quality Socket Cap We Can Supply
SSM manufactures socket caps and pipe fittings primarily designed to seal the ends of pipes. These fittings have a socket end that matches the pipe interface, commonly used to prevent fluids or gases from leaking from the pipe end and to protect the interior of the pipe from external environmental factors. The socket caps we provide include the following types:
NPS | 1/8 | 1/4 | 3/8 | 1/2 |
3/4 | 1 | 1 1/4 | 1 1/2 | |
2 | 2 1/2 | 3 | 4 | |
Class Designation | 3000 | 6000 | 9000 | |
Material | A105, A182, A350, B462, or B564. |
The Materials of Socket Cap We Can Provide
SSM’s socket caps are manufactured from controllable raw materials with strict quality control. We commonly supply fittings made from the following materials:

Carbon Steel Socket Cap
SSM produces Carbon Steel Socket Caps from strong and durable carbon steel, ideal for cost-effective and high-strength piping systems.
Common Grades: ASTM A105, ASTM A350.

Stainless Steel Socket Cap
SSM offers stainless steel Socket Caps, providing exceptional corrosion and oxidation resistance. Ideal for applications requiring high corrosion resistance, especially in corrosive environments or under high-temperature conditions.
Common Grades: ASTM A182 F304/F304L , ASTM A182 F316/F316L

Alloy Steel Socket Cap
SSM offers Alloy Steel Socket Caps with exceptional high-temperature strength, wear resistance, and oxidation resistance. Alloy steel typically contains added alloying elements such as chromium, molybdenum, and nickel, which enhance the material’s mechanical properties and durability.
Common Grades: ASTM A182 F11, ASTM A182 F22.

Nikel Alloy Socket Cap
Nickel alloy socket caps are crafted from nickel alloy, known for its exceptional corrosion resistance and high-temperature performance. Nickel alloys usually consist of nickel along with other alloying elements like chromium and copper, which improve the material’s resistance to corrosion, wear, and oxidation.
Common Grades: Inconel 600, Inconel 625, Monel 400, Hastelloy C276.
Application of Socket Cap
- Oil and Gas Industry
- Chemical and Pharmaceutical Industry
- Water and Wastewater Treatment
- Boiler and Pressure Vessel Systems
- Hydraulic and Pneumatic Systems

Pros & Cons of Socket Cap
Socket caps have several advantages, including effectively preventing leaks by sealing the ends of pipes and protecting the interior from external contaminants and damage. They are versatile and suitable for various industries, providing a simple installation process for both temporary and permanent pipe closures.
However, socket caps have limitations. They can only be used at the ends of pipes and cannot facilitate connections or branching. They may be ideal for high-pressure or high-temperature applications with additional reinforcement, but their materials may be prone to corrosion over time. Additionally, frequent access to the pipe end can be challenging, as the caps need to be removed.
