T type. Elbow type pipe fitting end cap
Pipe fitting end closure
Used to lock the pipe test sample, the end closures seal off the sample in order to generate internal pressure in the sample. Maximum pressure depends on standard, specifications and pipe sample diameter. The design of the small end closure device for small diameter and large diameter pipe samples is different from the design of medium and large end closure devices.

What's the End cap of pipe pressure test?
Understand the pipe end cap for hydrostatic pressure test:
The hydrostatic pressure test end cap is specialized equipment used to detect the pressure-resistant performance of pipes, primarily used for static hydraulic tests and burst tests of plastic pipes (such as PVC, PE, PPR, etc.). It conducts pressure testing by sealing the ends of the pipes to assess their long-term static hydraulic strength and pressure resistance.
Core Functions:
Sealing Test: Achieved through silicone sealing rings and radial sealing design, firmly sealing the ends of the pipes to prevent liquid leakage during testing.
Specification Compatibility: Supports various diameters (such as Φ16-Φ1600mm), suitable for testing the requirements of different materials such as PVC, PE, PPR, and composite pipes.
Compliance with Standards: Adheres to national standards such as GB/T 6111 and GB/T 15560, as well as international standards like ISO 1167.
