NPTLOK Union Elbows

NPTLOK union elbow has two tube fittings ends to connect two tubings at a 90° angle. A union elbow is designed with very stringent tolerance to provide a free leak, and torque-free seal on tubing connections. A union elbow consists of a body, a front ferrule, a back ferrule, and a nut. The body is forged parts or bar stock depending on the customer’s requirements. A union elbow has all tube fittings ends, which have higher pressure than a male or female pipe end.

NPT Fittings Materials

Materials Choices

NPTLOK union elbow is available in stainless steel, brass, carbon steel, or special materials like Monel, and Alloy.

When you choose materials, stainless steel tubing should not be used with brass fittings, as tubing materials should be softer than fitting materials. When tubing and fittings are made of the same material, The tubing should be annealed.

Bar Stock Or Forging Body Is Available

NPTLOK union elbow is available in bar stock body or forging body depending on customers’ requirements.

A forging body is a good choice for high-temperature and high-pressure systems. During the forging process, the metal’s grain structure is becoming more refined, which increases the impact and overall strength of the body.

If your fluid systems require high temperatures and pressure materials, the forging body is a good choice.
