Stock the all-JIC tee when all three ports on the drawing carry a 37 degree cone. Stock the run tee when one port has to be an SAE O-ring boss. The run tee vs branch tee decision is not about which part is stronger. 

Every quote sheet has two columns, and the zinc-nickel column always costs more. Here is the short answer first: pay for zinc-nickel plating when your fittings see weather, salt or washdown. Stay with standard zinc plating when they live indoors on a fixed power unit. 

A hydraulic line that has to cross a tank wall, a frame plate or a manifold panel needs a sealed pass-through. The 6C metric bulkhead fitting does that job with two 24° cone light series ends, built to DIN 2353 and ISO 8434-1. This guide covers the size range, thread list, pressure ratings and the h

A practical guide to identifying metric hydraulic fittings by thread diameter, pitch, sealing surface, tube outside diameter and light or heavy series. It explains 24-degree cone and cutting-ring connections, common identification mistakes, the tools required for measurement, and the information buyers should provide before ordering a replacement.

The 1J9 is a 90-degree hydraulic elbow adapter with JIC male 37° flare ends on both ports. It connects two female JIC fittings or tube ends where a line must turn a corner without extra couplings.The 1J9 is a 90-degree hydraulic elbow adapter with JIC male 37° flare ends on both ports.
