How do I know a part fits my truck?

Every listing shows the truck make, model years, side (left/right) and OEM cross-reference numbers. Match any of your OEM numbers to the listing, or send us your number and we will confirm fitment.

Do you ship the same day?

Orders placed before 12PM Central on business days ship the same day from our US warehouse. Transit is typically 2–5 business days depending on your state.

What is your return policy?

30-day returns on unused parts in original packaging. Wrong part shipped by us? We cover the return label and ship the correct one first.

Do you offer fleet or shop pricing?

Yes. Business accounts get tiered pricing, saved reorders and a dedicated line. Open a business account to see your pricing and order online.

Are these OEM or aftermarket parts?

We sell quality aftermarket parts cross-referenced to OEM numbers, plus select OEM-grade lines. Brand and grade are shown on every listing.

Can I order by part number?

Yes — type any part number or OEM cross reference into the search bar. If it is not listed, send it to us and we will source it.

Air Check Valve, Specifications & Fitment

One-way air check valve for Mack and Volvo air systems. It allows air to flow in a single direction and blocks reverse flow, holding pressure in a circuit and protecting components such as accessory or air-suspension lines from backfeed when supply pressure drops. Replace it when air bleeds back, a circuit will not hold pressure, or the valve leaks or sticks.

Specifications

Inlet thread: M22 x 1.5
Outlet: 1/2in tube, push-lock (PLC)
Function: One-way (non-return) check valve

Where it's used

Mack and Volvo air systems. Threads into the air manifold or port and connects to a 1/2in air line on the protected circuit.

Cross references: Volvo 20999392
