Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • 7.50-20 tube-type service truck tire on a 20-inch rim
  • 7.50R20 tire approved for tube use on a 20-inch rim
  • Truck wheel assemblies specified for a TR441 valve-stem position

Product Overview

A roadside-service tire that slowly loses air after a puncture repair may still have a pinched tube, rough rim, valve-base crack, or hidden casing damage. This tube belongs in an assembly that has been fully dismounted and inspected—not used to cover up a damaged tire.

The tube provides the air chamber for compatible 20-inch tube-type truck tires. TR441 stem position and angle must match the rim so the stem is not pulled when the tire flexes.

Key Features & Performance

  • Fits listed 7.50-20 and 7.50R20 tube-type tires
  • TR441 metal valve stem
  • Sized for a 20-inch service-truck rim
  • Replacement for puncture, seam, or valve-base failure

Replaces Part Numbers

  • TR441

Common Uses

  • Replacing a punctured truck tire tube
  • Correcting a leak at the tube valve base
  • Renewing an aged tube during tire replacement
  • Completing a professional tube-type service-truck tire repair

Technical Specifications

  • Product Type: Truck Tire Inner Tube
  • Tire Sizes: 7.50-20 and 7.50R20
  • Rim Diameter: 20 in

Installation & Fitment

  • Fully deflate the assembly before dismounting or touching rim hardware
  • Confirm tire construction, rim diameter, flap, and TR441 stem position

  • Install without folds, use proper restraint for inflation, and leak-test before mounting on the vehicle

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.

Production date, serial number, engine option, dimensions, connections, and previous repairs can change the part used within the same model. Compare the removed item and service information before purchase.

Frequently Asked Questions

Q: Can this be used in a 7.50R20 radial tire? A: Only if the tire and rim are designed and approved for tube use. Confirm the tire maker’s service information.

Q: Do I need a new rim flap? A: Inspect the flap for hardening, tears, folds, and exposed rim edges. Replace it whenever it cannot protect the tube correctly.

Q: Why should I compare the removed part? A: Use the compatible list as a starting point, then compare the original reference number, dimensions, connections, mounting details, production date, and equipment or engine serial information.

Q: Is this a factory-branded component? A: This is a new aftermarket part. The brand and model names identify the applications it is intended to service.
