Thomas & Betts 429 – Frequently Asked Questions
1) What size conductor or connector does the Thomas & Betts 429 sleeve cover?
The 429 is sized to a 3 inch nominal cross section, so it is matched to connectors and terminations of that nominal size rather than being a general-purpose cut-to-fit tubing. Match the sleeve to the nominal size of the lug or splice you are insulating, not to the bare conductor diameter.
2) What is the Thomas & Betts 429 insulating sleeve made of?
Nylon. That gives it a rigid, self-supporting body that slips over a termination and stays put, unlike heat shrink or tape which need heat or wrapping labor. For electricians doing repetitive terminations in a panel, the slip-on nylon sleeve is the faster install.
3) How many Thomas & Betts 429 sleeves come in a box?
They pack 5 to the inner carton and 10 inner cartons to the outer, so a full outer case is 50 pieces. Contractors buying for a full panel build should order by the outer case; a single inner pack of 5 suits a service truck restock.
4) What is the exact part number to order the Thomas & Betts insulating sleeve?
Order it as Thomas & Betts 429. That is the manufacturer part number, and it is the single model this sleeve is sold under, so there is no size or finish suffix to specify on the purchase order.
5) How big is the shipping carton on the Thomas & Betts 429 sleeve?
The outer carton measures 9.8 x 6.9 x 4 inches and the product weight runs 1.5 lbs per 100 pieces. Useful if you are staging material on a job cart or working out freight on a bulk order.
