ADAPTORS
FINDING ADAPTORS
There are three easy rules to remember to quickly find an ADAPTOR in this section. These are, in order:
RULE 1. ALPHABETICAL RULE
The ADAPTORS section follows THREAD or CONNECTOR TYPE order and is in the “ALPHABETICAL” sequence shown on the Contents Page opposite. (This order is strictly alphabetical; except for NPT, which is similar in concept to BSP and is placed directly after BSP; and RYCOLOK, SUPERLOK and RYCO WEO which are placed at the end of the ADAPTORS section).
RULE 2. MIXTURE RULE
Where there is a MIXTURE of THREAD or CONNECTOR TYPES eg. JIC one end UNO other end, this adaptor will be found in the JIC section (because JIC comes alphabetically before UNO). All the JIC/JIC adaptors come first, then JIC/ORFS then JIC/UNO.
There are SEVEN EXCEPTIONS to this MIXTURE rule:
METRIC
SAE FLANGE RYCOLOK SUPERLOK RYCO WEO
In these cases, the METRIC, SAE FLANGE, RYCOLOK, SUPERLOK or RYCO WEO end takes precedence. All METRIC adaptors, regardless of other end mixture, are in the METRIC group, and all SAE FLANGE adaptors are in SAE FLANGE group. Therefore a JIC/METRIC nipple will be found in METRIC Section not JIC Section; and an SAE FLANGE/BSP adaptor is in SAE FLANGE section not BSP section.
RULE 3. NUMBER OF ENDS RULE
Within each subsection the order is as follows:
FIND BY END NUMBER
ONE ENDED ADAPTORS PLUG Male Plugs before Female Caps. CAP
TWO ENDED ADAPTORS
TUBE WELD
NUT & SLEEVE/NUT & OLIVE STRAIGHT
45o ELBOW
90o ELBOW
45o TUBE BEND
90o TUBE BEND
Male/Male before Male/Female before Female/Female
THREE ENDED ADAPTORS
TEE Y
Male Tees
before Male/Female Tees before
Female Tees
FOUR ENDED ADAPTORS
CROSS X
OTHER WAYS TO QUICKLY FIND AN ADAPTOR
1. CONTENTS PAGE on page 389
2. ALPHANUMERIC INDEX on pages 4 and 5
3. PICTORIAL INDEX on pages 393 to 400
The PICTORIAL INDEX is in NUMBER OF ENDS rule order except 45o TUBE BENDS are after 45o ELBOWS, and 90o TUBE BENDS are after 90o ELBOWS.
All PLUGS first, then CAPS, TUBE WELDS, etc. finishing with CROSSES except all SAE FLANGES, SAE FLANGE BLOCKS and all RYCOLOK, SUPERLOK and RYCO WEO are at the end of the index.
