About Thread-reducers

The thread reducer adapts two different female threads to each other, in this case G 3/4 to G 1/4. It belongs to the speedfit push-in range and is released for working pressures from -0.95 to 16 bar, which includes vacuum duty.

What matters when choosing

• Thread pairing G 3/4 female to G 1/4 female: both sides are female, so each mating part has to carry a male thread.
• Working pressure -0.95 to 16 bar covers vacuum operation as well as the usual mains pressure of compressed air distribution.
• Material acetal polymer (POM): light, abrasion resistant and impact resistant, but no substitute for metal where high tightening torques are applied.
• speedfit series: the reducer is matched to the rest of the push-in programme of that series.
• Approvals: the POM push-in fittings carry the drinking water approvals DVGW, KTW, FDA and NSF.

Typical applications

• Adapting the port thread on service units and manifolds
• Drinking water installations that call for a corresponding approval
• Joining plastic and metal pipe in plant engineering
• Vacuum lines on suction cups and handling equipment
• Test set-ups that are frequently changed over to other port sizes

The material is acetal polymer (POM), and the push-in fittings of this series are approved for drinking water to DVGW, KTW, FDA and NSF. Country of origin is Germany (DE).
