Couldn't load pickup availability
The General Pump 701016 is a genuine OEM replacement O-ring for General Pump plunger pumps and related components. It measures 15.6 mm diameter × 1.78 mm thickness and is made from Buna-N (nitrile) rubber with a 70 durometer hardness, a firm, general-purpose compound that holds its shape under pressure while still sealing reliably. It’s rated to a max temperature of 250° F, making it suitable for cold-water and many warm-water pressure washer applications, and nitrile resists water, oils, and many common cleaning solutions.
O-rings harden, flatten, or crack over time from heat, pressure cycling, and chemical exposure, which can cause drips, seepage, or pressure loss. Replacing worn O-rings during routine service restores a tight, leak-free seal and helps protect more expensive pump components.
