Mastercool 70053 — 45° Flaring & Swaging Tool Set (1/8" to 3/4") with Carrying Case

Complete Flaring and Swaging Solution: 9 Flaring Sizes, 7 Swaging Sizes, One Professional Kit

The Mastercool 70053 45-degree flaring and swaging tool set is the complete solution for professional refrigeration and plumbing work. Featuring a durable forged steel slip-on yoke, chrome-plated hardened steel bars, and five swaging adapters, this kit covers 9 flaring sizes (1/8" to 3/4") and 7 swaging sizes (3/16" to 3/4"). The swaging adapters work in close quarters where punch-style tools cannot be used, whilst the custom plastic carrying case keeps everything organised and protected.

Forged Steel Slip-On Yoke: Built for Professional Use

The durable forged steel slip-on yoke provides superior strength and longevity compared to cast yokes. Forged steel construction resists cracking under pressure and delivers reliable performance year after year. The slip-on design makes it easy to position tubing quickly, speeding up both flaring and swaging operations.

Chrome-Plated Hardened Steel Bars: Precision and Durability

The chrome-plated, hardened steel flaring bars maintain dimensional accuracy even after thousands of operations. The hardened construction ensures the bars don't wear or deform, whilst the chrome plating provides corrosion resistance and a smooth, polished surface for easy tubing insertion and removal.

Swaging in Close Quarters: Where Punch Tools Can't Reach

The five swaging adapters allow swaging in close quarters where traditional punch-style swaging tools cannot be used. This is a game-changer for tight installations — instead of removing components or struggling with bulky punch tools, you can swage tubing in place using the compact adapter design.

Why This Matters: Swaging is often needed in tight spaces — behind equipment, in confined compartments, or in existing installations. The 70053's swaging adapters solve this problem, allowing professional swaging work even in the most cramped locations.

Complete Kit with Carrying Case

The custom plastic carrying case keeps all components organised and protected. No more lost adapters or damaged bars — everything has its place in the moulded case. Perfect for mobile service operations or organised workshop storage.

What is Swaging?

Swaging is the process of expanding the end of a tube so another tube of the same size can fit inside it, creating a slip-fit connection. This is commonly used in:

• Refrigeration Line Sets — Connecting field-fabricated lines
• Plumbing Repairs — Joining copper tubing without fittings
• HVAC Installations — Creating custom-length line sets
• Tight-Space Repairs — Where couplings won't fit

Swaging vs Flaring: When to Use Each

Use Flaring When:

• Connecting tubing to threaded fittings
• Creating reusable connections
• Working with manifolds, valves, or equipment ports
• SAE standard connections are required

Use Swaging When:

• Joining two tubes of the same size
• Creating permanent slip-fit connections
• Working in tight spaces where fittings won't fit
• Extending or repairing tubing runs

How to Create Perfect Flares with the 70053

1. Cut Tubing Square — Use a proper tubing cutter
2. Deburr Inside and Outside — Remove all burrs
3. Slide Flare Nut On — Don't forget before flaring!
4. Select Correct Bar — Choose bar with correct size
5. Position in Flaring Bar — Insert to correct depth
6. Slip Yoke Over Bar — Forged steel yoke design
7. Turn Handle — Create 45-degree flare
8. Back Off and Inspect — Check for smooth, even flare

How to Swage Tubing with the 70053

1. Cut Tubing Square — Clean, square cut is essential
2. Deburr Inside and Outside — Remove all burrs
3. Select Correct Adapter — Choose adapter for tubing size
4. Install Adapter in Yoke — Replace flaring cone with swaging adapter
5. Position Tubing — Insert tubing to correct depth
6. Turn Handle — Adapter expands tubing end
7. Back Off and Test Fit — Check that mating tube fits properly
