1/2 in FNPT 316 Stainless Cap

This Zoro Select cap provides a threaded closure for 1/2 inch nominal pipe size systems. It is manufactured from 316 stainless steel for corrosion resistance in industrial plumbing applications. The fitting suits Schedule 160 pipe and carries a Class 3000 pressure rating.

ASTM A182 Class 3000 Rating

The Class 3000 designation under ASTM A182 confirms the pressure-temperature capability required for high-pressure service. This single specification determines whether the fitting matches the design limits of the piping system. Verify the class rating against your engineering requirements before installation.

Threaded Schedule 160 Integration

The female NPT threads connect directly to Schedule 160 pipe without welding or additional sealant. An outside diameter of 1 1/8 in and overall length of 1 1/4 in define the space needed inside the fitting assembly. The 316 stainless material eliminates the need for protective coatings in corrosive environments.

Questions about this item

What does the Class 3000 rating mean for a 1/2 in FNPT cap in a real piping system?

Class 3000 designates the pressure-temperature rating for this forged stainless steel fitting, indicating it is built to handle the higher stresses found in Schedule 160 piping systems.

How does the 1/2 in FNPT thread standard affect what this cap can connect to?

The 1/2 inch Female National Pipe Taper thread mates with a matching 1/2 inch male NPT pipe or fitting, creating a tapered seal that tightens as it is threaded.

What are the physical dimensions I need to confirm for installation clearance?

The cap has an outside diameter of 1 1/8 in and an overall length of 1 1/4 in, so verify that surrounding components allow space for this profile.
