Then let’s dive in!

What Is ProPEX Expander Cone Grease?

First things first – what exactly is ProPEX grease? Essentially, it’s a specially formulated lubricant designed for use with PEX tubing and expansion tools.

The key ingredients are:

ProPEX Expander Cone Grease
  • High-quality synthetic base oils
  • Thickeners to give the grease its consistency
  • Anti-wear additives to reduce friction and wear
  • Corrosion inhibitors to prevent rusting

ProPEX is made by the company Raven and optimized specifically for their brand of expansion tools and PEX fittings.

It helps the expander cone glide smoothly through the tubing during installation.

This prevents:

  • Damage to the tubing interior
  • Excessive friction and heat
  • Sticking/seizing of the expander

So in short – it’s a precision-engineered lubricant made to work flawlessly with ProPEX system components.

Why Consider Alternatives To ProPEX Grease?

Now you might be wondering – if ProPEX grease is specially formulated for ProPEX tools, why would I want to use anything else?

There are a few reasons you might want to explore alternatives:

  • Cost – ProPEX grease is one of the most expensive PEX lubricants out there. A 14 oz tub costs around $25. For large jobs, that adds up fast.
  • Availability – The ProPEX brand isn’t universally stocked. Some supply houses may not carry it or might be out of stock.
  • Compatibility – Other high-quality greases work just as well with ProPEX components. So you don’t have to be brand-loyal to get great results.
  • Performance – Some plumbers claim certain alternative greases actually outperform ProPEX grease, keeping tools sharper for longer.
  • Environmental Factors – ProPEX grease performs best in certain temperature/humidity ranges. Alternatives may hold up better in extreme conditions.

The bottom line is you have options. And you may be able to get equal or even better performance while saving money.

Which Is The Best ProPEX Grease Alternative?

At the end of the day, there is no single “best” ProPEX grease substitute. All the options above will work well, with just some slight performance tradeoffs.

Here are some quick tips on choosing the right one:

  • Lubripex – Best all-around value and performance
  • Oatey Pipe Dope – Best super-cheap grease option
  • Blue Magic – Best for maximum slickness
  • Slickon Spray – Best for convenience and ease of application

My personal favorite is Lubripex – it delivers great performance for PEX at a fraction of the price of ProPEX grease.

But evaluate your specific needs. For cold weather installs, a silicone spray like Slickon may be ideal. For a Smokey chemical-free lube, Blue Magic is a top choice.

You really can’t go wrong with any of these well-proven alternatives.

Application Tips For ProPEX Grease Alternatives

Once you’ve selected your ProPEX substitute grease, proper application is key. Here are some quick tips:

  • Completely clean expander cone first – remove all dirt, debris, old grease etc.
  • Apply a generous layer of grease to the cone – don’t skimp!
  • Use a small disposable brush or glove for smoother application
  • Reapply frequently during longer jobs – every 5-10 expansions
  • Keep grease off tubing interior to prevent expansion issues
  • Wipe tool clean after use to prevent dirt buildup
  • Store grease properly between use to prevent hardening

Take the time to thoroughly coat the cone and reapply as needed. This will ensure smooth expansions and prevent wear on PEX tools.

Pro tip: Lubricate O-rings on the expander with a small dab of grease as well. This prevents drying out and damage.
