Parker O-Ring Kits: First Aid For Your Equipment


Parker O-Ring Kits Are First-Aid for Your Equipment

They say an ounce of prevention is worth a pound of cure. You keep first-aid kits on hand in case something unexpected happens to one of your people. But what if some unexpected thing happens to your equipment or product? Will it be a minor bump in the road or a major hassle? That depends on your preparation.

Expect the Unexpected

Whether you’re an operator, a manufacturer, or a repair shop, someday, you’re going to find yourself missing an o-ring that you need right now. You’re diligent in managing your inventory, and it’s obviously not cost effective to keep a large inventory of every part you may potentially need on hand at all times. But life, especially where it involves machinery, is full of surprises. And, just like that first-aid kit ensures that you have solutions for the most commonly experienced mishaps for humans, a well-designed o-ring kit keeps your business running smoothly.

Perhaps you get more warranty work than expected, maybe there’s a manufacturing issue that causes excess waste, maybe there’s a blizzard that delays your shipment from your supplier. Whatever the reason, you’re going to be left in a holding pattern if you don’t have a backup supply to tide you over. If an o-ring fails in the field, having a kit on the equipment may make the difference between a quick repair and a lost day.

Stack the Odds in Your Favor

Parker offers standard assortment kits of 0-rings in metric and SAE sizes, in nitrile (NBR) or fluorocarbon (FKM). Each standard kit includes assorted sizes of O-rings, for a total of about 500 pieces, depending on the kit. The compact kits are housed in a durable box, neatly organized and labeled, to speed you through urgent situations.

  • Kit #1 – Supports most American-built equipment, and contains 30 of the commonly needed o-ring sizes.
  • Boss Seal Kit – Designed with hydraulic fittings in mind. The Boss Seal Kit includes all 20 standard tube fitting seals, for tube opening diameters ranging from 3/32" to 2".
  • Metric Kit #1 – Supports equipment made overseas, and contains 32 of the most commonly used metric-sized o-rings.


The standard kit and metric kit feature 70-durometer nitrile, which is compatible with petroleum grease and oil, hydraulic fluid at temperatures up to 250°F, and water glycol hydraulic fluid up to 120°F

The Boss Seal Kit includes o-rings made of 90-durometer nitrile, compatible with higher pressure systems. This kit can be upgraded to FKM material for more demanding applications.
