This document contains procedure guidelines for the conversion from both water free and water based hydraulic fluids to QUINTOLUBRIC® 888.
Compatibility of QUINTOLUBRIC® 888 Series with NBR Seal Material
Joseph Frio2019-04-11T15:49:21-04:00One of the main considerations when choosing a hydraulic fluid, is it’s compatibility with seals. More specifically it’s compatibility with Nitrile Butadiene Rubber (NBR) seals. NBR is the most cost effective and commonly used seal type in hydraulic systems. This elastomer found in various hydraulic unit applications.
Particle Counting
Joseph Frio2018-10-04T17:28:14-04:00Most component failures are the direct result of contaminated hydraulic oil, and the expense of having to replace hydraulic components damaged by contamination is often eclipsed by the even higher cost of unscheduled downtime for the machine. Learn how hydraulic fluid cleanliness can be measured using several techniques and reporting methods.
Relativity of Acid Number for Hydraulic Fluids
Joseph Frio2018-10-04T17:21:31-04:00The total acid number (TAN) is an analytical test to determine the deterioration of lubricants in service due to oxidation. As a fluid degrades with oxidation, the viscosity increases as well as the levels of corrosive acids, soot and varnish, along with the danger of component failure.
Service Guide for QUINTOLUBRIC® 888 Series
Joseph Frio2019-04-11T15:25:44-04:00Monitoring through in-service oil analysis, an important element of predictive maintenance, can provide information about machine wear, as well as lubricant contamination and condition. By checking the appearance, viscosity, water content, acid number, cleanliness and solid metal and additive contents, the condition of the fluid can be measured.

Water Quality
guest author2017-10-13T17:08:13-04:00Cutting and grinding coolants, diluted for use, are mostly water (95% water at a typical concentration). Water plays an important role in coolant performance. We need to understand how water affects metalworking coolants. This “Skill Builder” makes water crystal clear.
QUINTOLUBRIC® Q-Trak
guest author2017-11-21T21:14:10-04:00Quaker manufactures and sells fire resistant hydraulic fluids (FRHFs) under the brand name QUINTOLUBRIC®. Routine analysis of these fluids is sent to Quaker laboratories in Conshohocken, PA to the Q-TRAK lab. This lab assesses the FRHFs in a number of areas as detailed in this “Skill Builder.”
Tramp Oil
guest author2017-10-13T16:00:29-04:00Tramp oil is probably one of the most common contaminants in metalworking fluids. Whatever the source, tramp oil is a foreign contaminant that can create the problems detailed in this “Skill Builder.”
Samples
guest author2017-11-20T14:59:58-04:00At some point in time it becomes necessary to take a sample of a fluid for some type of analysis. However, not all fluids should be sampled in the same manner.
Recycling Fluids
guest author2017-10-13T15:59:17-04:00The concept of recycling fluids has been around for a while. The focus of waste reduction is typically called “Reduce, Reuse & Recycle.”
