ABOUT COMPRESSION FITTINGS

Compression fittings are the most basic style of tube fitting made. The fitting is made up
of 3 parts to complete a joint, these being an olive, nut and body. The joint is made by
inserting the tube down to the tube stop and tightening a nut which conforms the olive to
the shape of the radius and taper of the body and nut.
There are 2 styles of Olives available The are Standard Olives (No 1) and universal
olives (No 100). The compression fittings come standard with the No 100 Olive as not
only is universal in application but also has a step in design to reduce the possibility of
over tightening.

PRESSURE

1/8' - 1/2" Max 1250PSI/8600kPa Hydraulic @25ºC depending on tubing
5/8',3/4" Max 500PSI/3450kPa Hydraulic @25ºC depending on tubing
(Please use manufacturers working pressure on tubes for correct working pressure).

MATERIAL

Imperial Compression - Brass
Metric Compression - Brass & SS 316

TUBES USED WITH

Polyurethane
Nylon - NOT AIRBRAKE
Aluminium
Copper
Brass
DO NOT USE WITH BUNDY TUBE

TYPICAL APPLICATION

Metric and Imperial Compression Fittings are mainly used in Hydraulic and Pneumatic
Systems. With their low cost and ease of assembly Compression Fittings have become a
good option for connecting different kinds of tubes.

TEMPERATURE RANGE

Brass -53C to + 121C
Stainless Steel

THREADS

BSP - British Standard Pipe Taper
NPT - National Pipe Thread (limited)

ASSEMBLY

1. Cut tubing to desired length ensuring tube cut is square and clean
2. Slide Nut and olive on Tube (Threaded end of Nut must face toward fitting)
3. If using plastic tubing a spigot MUST be used in tube
4. If using metal tube no spigot needs to be used
5. Insert tubing into fitting body. Be sure tubing is unable to be inserted any farther
6. Lubricate threads with Tape or sealant and assemble nut to body of fitting
7. Tighten nut hand tight. From that point tighten with a spanner DO NOT
OVERTIGHTEN.
