When the spring in your Hydrofarm precision pruners eventually gets a bit tired, don't send them to the recycling bin. Make them like new again with a replacement pruner spring. These bouncy springs slip quickly and easily into place on the precision pruner so you'll be back to snipping in no time. Models it is compatible with include HGPP400C, HGPP400, HGPP400T, and HGPP400CT. May also fit other brands.
Dimension of spring is 1.26" length (32 mm), .318" width (8 mm)
