Value Brand

Value Brand 1 in Female Coupler 316 SS Dust Cap

SKU CH-2NPN-VABR1

A 316 stainless-steel dust cap protects a 1-inch female coupler socket at up to 250 psi working pressure

  • 316 stainless steel resists corrosion in harsh environments
  • Female 1 inch coupler fits standard plumbing connections
  • 250 psi working pressure handles demanding fluid systems
  • Nitrile gasket provides reliable sealing at 70 F
  • Locking arm included for secure dust cap attachment

Product Identity

This Zoro Select dust cap is a 1 in female coupler socket made from 316 stainless steel. It fits Type DC couplings and includes a locking arm for secure closure. The nitrile gasket seals against 250 psi at 70 F. Buyers protecting idle hydraulic or pneumatic lines will find it suitable.

Installation Check

Verify the existing coupler uses a Type DC interface and a 1 in female connection before ordering. Confirm the system pressure does not exceed 250 psi at 70 F. Ensure the nitrile gasket material is compatible with the fluid or gas in the circuit. The socket inside diameter measures 1 15/32 in.

Upgrade Context

This cap replaces lost or damaged dust covers on compatible quick-disconnect sockets. The jump is worth it when the original cap is missing and contamination risk is high. It also upgrades from plastic or carbon-steel caps where corrosion resistance matters. The 316 stainless body resists rust in harsh environments.

Questions about this item

Does the 1 inch female coupler dust cap come with a gasket or must I order one separately?

The cap includes a nitrile gasket and a locking arm, so no extra sealing parts are required.

When should I choose the 316 stainless steel version instead of another material for a 1 inch coupler?

316 stainless steel resists corrosion in chemical and marine environments, making it the choice when the fluid or atmosphere is aggressive.

What does the 250 psi rating at 70 F mean once the cap is installed on a 1 inch line?

It guarantees the cap will hold up to 250 psi at 70 F; at higher temperatures the safe working pressure will be lower.
