## Description

300 Mini Pumps are designed for convenient and accurate metering of Group A, B, and C WEST SYSTEM 105 Resin-based epoxy. The 300 Mini Pump Set Contains one resin pump and two hardener pumps. Pumps mount directly on the resin and hardener containers and eliminate the mess involved with measuring by weight or volume. These pumps are calibrated to deliver the proper working ratio with one full pump stroke of resin for each one full pump stroke of hardener. 105/205-206 pumps deliver approximate 0.8 fl oz of resin/hardener with one full stroke of each pump. 105/207-209 pumps deliver approximately 0.9 fl oz of resin/hardener with one full stroke of each pump. Made of durable polypropylene, the Mini Pumps give years of dependable service. Read and follow the priming, ratio verification and operating instructions that come with the pumps. As packaged, the pumps are ready to install on the Group Size B containers. A package of extension tubes for Group Size A containers is included with the set. Group Size C extension tubes are included in the 105-C Resin and in the 207-SC or 209-SC packages.

Review: The only way to mix epoxy - These pumps are perfect for mixing epoxy and make it easy to get the ratios correct. I appreciate that the cans and pumps are designed so they are mistake proof from mixing up pumps with resin and hardener.
Review: Top Quality Epoxy System - I have been using the West System 5:1 epoxy system for over 15 years, and have been extremely satisfied with the consistency and results....so much so that I decided to treat myself to this new set of metering pumps. I do a lot of small batches and these pumps make that task so easy!

### ⭐⭐⭐⭐⭐ Top Quality Epoxy System
*by Y***K on February 15, 2019*

I have been using the West System 5:1 epoxy system for over 15 years, and have been extremely satisfied with the consistency and results....so much so that I decided to treat myself to this new set of metering pumps. I do a lot of small batches and these pumps make that task so easy!

### ⭐⭐⭐⭐⭐ There is also extension tubing included for if you need to fine tune the length of the nozzles
*by G***Y on November 11, 2016*

These worked perfectly. I was irresponsible and did not do a "test pour" to check if the proportions were right. I literally came home from work, slapped these things onto the 105 resin and 207 hardener, went through half a gallon of 105 and 1/6th gallon of 207. No problems with the curing/hardening process. I did see someone else comment negatively about how the plastic was brittle and broke for them after a couple pumps. Because of that I was cautious at first but after a while I saw that point was null and void. I was not gentle with these suckers, I just went to town on them. Included hardware notes: This comes with the 3 nozzle heads you see in the picture, 1 is for the resin, 2 are different sizes for hardener containers of differing spout sizes. There is also extension tubing included for if you need to fine tune the length of the nozzles.
