If you have broken a plunger or just need a spare you can order them here, we stock the smaller ones as they are the most commonly overloaded.

Plungers break when they are overloaded, not inserted correctly or aligned with the pressing surfaces. The most common is when they are overloaded and this is particularly true with the smaller ones where a few pumps of the hydraulic press handle can lead to very high stresses on small-cross sectional area of the plunger.

We have tested our plungers and made 1000s of them. Please don't push the limits and please use within the recommended limits on the product page. If you are using enough force to break high strength heat treated steel, this is more than enough to compress powders together. 

If you are using high pressing forces then please check out or low profile die sets.

The plungers' height is 41 mm (1.61 inches) for diameters under 10 mm (0.39 inches) and 51 mm (2.01 inches) for diameters above 10 mm (0.39 inches); excluding the knurled knob at end of plunger.

Please note that these plungers are for the standard height die sets only, they are not suitable for the tall die sets. If you need a replacement plunger for a tall die set or another type of die set, please email us or complete our quote form.

We offer spare plungers in both D2 Tool Steel and Stainless Steel. If you have a D2 Tool Steel die set, we recommend purchasing a D2 Tool Steel plunger. Using a Stainless Steel plunger with a D2 Tool Steel die set will not increase the force capacity of your die set. The max load of the set is related also the base plate and sleeve, and exceeding the recommend max stress of the set will compromise it making it unsafe. Load ratings for your die set can be found on the die set product pages. 

Press safely!
