We have collected the questions we are asked most often at the counter and on the phone, complete with dimension tables. Use these pages to identify the part in your hand and order the right product.
A JIC fitting is an inch-sized connection that seals through a 37 degree flare seating metal against metal. This page gives the size table, thread equivalents and guidance on when to use it.
An ORFS (O-Ring Face Seal) fitting uses an O-ring in its end face so the joint does not leak even under vibration. Size table, working pressures and a comparison with JIC.
If you do not know the size of the fitting in your hand, this page is all you need. Measure the outside diameter with a caliper, find it in the table, and compare metric, BSP, JIC and ORFS sizes side by side.
A wrongly chosen hose either bursts early or stops the machine. We work through the seven questions that need answering when selecting a hose — from size and pressure to temperature and end type.
The 1SN, 2SN, 2SC and 4SP markings printed on a hose describe its reinforcement. We explain how many wire layers each has, what pressure it holds and where each one is used, with tables.
BSP and NPT look alike but do not fit — one is 55° and the other 60°. This page covers the differences between the three thread standards, how to tell them apart and where each is used.
Send us a photo of the part along with a caliper measurement. We will identify the size, tell you the matching product and confirm stock.
