Push-Fit Elbow for Vacuum Lines

This push-fit elbow fitting joins an 8 mm tube to a 1/4 inch MBSPT port. The body is moulded from fibre-glass-reinforced nylon and includes pre-applied thread sealant. It is rated for 290 psi and 175 °F maximum operating conditions. The black component is supplied new and ready for installation.

Suitable Uses and Limitations

The fitting suits vacuum applications that require a 90-degree change of direction between metric tubing and imperial pipe threads. It will not work where a straight connector, a tee or a different thread standard is needed. Buyers needing a larger tube diameter or a higher temperature rating must choose another part.

Critical Specification

The decisive detail is the Side A tube outer diameter of 8 mm paired with a Side B pipe size of 1/4 inch MBSPT. Both dimensions must match the existing tubing and port exactly, otherwise the fitting cannot seal.

Questions about this item

How do I install the 8mm push-fit side and the 1/4 MBSPT thread without cross-threading?

Push the 8mm tube straight in until it seats; for the 1/4 MBSPT thread, hand-tighten then turn one to two full turns using the pre-applied sealant — do not over-tighten the nylon body.

What maintenance or replacement will the fiberglass-reinforced nylon body and pre-applied sealant need later?

Inspect the push-fit grip ring and O-ring annually; replace the fitting if the nylon shows cracking or the sealant has washed out — the thread sealant is single-use.

Which limit appears first during sustained vacuum use at 175 Degrees F?

The 290 psi pressure rating is the governing limit; vacuum service stays well below it, so temperature (175 Degrees F) becomes the first constraint under continuous operation.
