The carbon steel market is poised to grow by 699.35 MT during 2020-2024 progressing at a CAGR of almost 8% during the forecast period." (Source: Business Wire)

This is what we are seeing all across the industry; day after day new emails from vendor's telling us that their prices are rising, every order we make for materials needs to be revised because the last price is no longer valid, and for good reason. The cost of steel materials has been steadily increasing throughout 2020, and it unfortunately has not slowed into 2021. The reduced capacities of companies in this industry due to Covid-19 health and safety regulations continues to have an impact. As a result, we are forced to increase our list pricing for 2021 and add a steel surcharge to off-set the rising costs that is projected to continue this year. We apologize for any inconvenience this may have on our close and prospective customers. We we will do what we can to keep our prices low when the opportunities are found, but right now we are left with little options.

Thank you for your understanding and continued support.


Product overview

QC Mate Quick Coupler Hand Clamp from XBoom


A common problem when connecting any quick-connect hydraulic coupler is that line pressure can build up, making connecting the couplers nearly impossible. The XBoom Coupler® QC-Mate(TM) quickly and safely solves that problem.

The QC Mate uses special shaped clamp jaws (13-ga steel tubing with large structural side gussets) that mount to a ratcheting hand clamp, providing powerful 600 lb clamping force. The Coupler Clamp is available in both 12" and 18" spacing to accommodate the various machines types and styles of hydraulic blocks and couplers. It is compatible with all standard Flat-Face Hydraulic Couplers and Ag Style Hydraulic Couplers within the listed sizes

Jaw Sizing

It is important to note the difference between the NPT size (commonly used for couplers) from the outer diameter of the coupler. When choosing QC Mate jaw sizes, select the jaw size that coincides with your coupler NPT size. If you have 1/2" quick couplers, select a 1/2" NPT jaw option. Be aware that the actual jaw width/diameter will be larger than 1/2" (.87" to be exact) in order to fit the outer diameter of the coupler.

Duo Jaws are designed to fit two sizes of coupler each. The benefit of this style is that you can use the same QC Mate clamp on two different coupler sizes without changing the jaws. The Duo Jaws are available in a smaller size (fits 3/8" & 1/2") and larger size (fits 1/2" & 3/4"). The disadvantage of the Duo style jaws is that when using them on the larger of the two sizes you may experience reduced clamping force because the connection with the coupler is less robust and closer to the "tip" of the jaw.

Actual Duo Jaw Diameters are:

  • 3/8" & 1/2" = .71" & .87"
  • 1/2" & 3/4" = .87" & 1.06"

Uni Jaws are designed to fit one size of coupler each, and they are available in 4 sizes. Uni Jaws are the most robust clamping jaw available because they keep the clamping force at the base of the jaw.

Actual Uni Jaw Diameters are:

  • 3/8" = .71"
  • 1/2" = .87"
  • 3/4" = 1.06"
  • 7/8" = 1.18"


  • 600 lb clamping force
  • 12" clamp width
  • 13 Gauge steel jaw material
  • 3/8", 1/2", 3/4", and 7/8" jaw sizes available

What's Included?

  • QC-Mate (TM) clamp (select size in options)
  • Installed set (2) of jaws (select jaw type in options)
  • Original IRWIN Jaw Pads and Stand
  • Spare pins (2)
  • Spare washers (4)
  • Owner's manual
  • Additional jaw set (2) - OPTIONAL
  • Additional pin kit - OPTIONAL

Will the QC-Mate work for my machine?

This tool is compatible with ALL standard 3/8", 1/2", 3/4", and 7/8" NPT nipples and fittings that attach to the back-side of Flat-Face and Ag Style Hydraulic Couplers. However, the Clamp Jaws need to engage the back-side of each coupler. Therefore, this device may not be compatible with some “Hydraulic Blocks” where access to both sides of the circuit are not accessible (this is the case with many CAT and Kubota skid steers and CTLs). Also, pre-measure your longest connection point distance (the spread) to determine whether you'll want the 12" or 18" clamp option. For the jaws to engage, you have to have access to the flat surfaces on the back of the couplers and a “shared center-line” for the clamp to align correctly and create an in-line clamping force.
